I. INTRODUCTIONRecently, the demands for the use of computer,

communication, and electronics devices have been

increased exponentially with development of new computer

network technology and electronics devices many of these

applications [1] require the use of wireless sensor

technology, which is the combination of computer network

technology plus electronics devices. The electronics

devices which are used in the wireless sensor technology

are known as sensor nodes. These sensor nodes typically

consist of sensor, transceiver, microprocessor, memory,

battery, and actuator. To measure the environmental

conditions such as temperature, pressure, sound, vibration

and natural disaster, these autonomous devices are typically

spatially distributed in an area. In case of an event, the

sensor converts any physical phenomenon into an electrical

signal while the actuator does the reverse. The transceiver

is a combination of transmitter and receiver, which is used

to transmit and receive signal and the memory, is used to

store the data.

The wireless sensor network (WSN) is a multi-hop

communication network, where hop-to-hop communication

is not possible. A source node near to sink node transmit

the information directly whereas, a sensing node which is

far away from the sink node transmit through intermediate

nodes or data forwarding node until it reached the

destination[2]. The sink node is directly connected to the

internet or satellite which is working like a gateway of the

network. Due to small size, low cost the smart sensors

(Micro-Electro-Mechanical-System) are used very often

now-a-days compares to conventional sensor nodes [3]. In

a WSN all the important functions such as frequency

selection, carrier frequency generation, modulation andlastly data encryption were done in physical layer [2]. The

WSN applications are broadly classified into two categories

such as, monitoring and tracking. Most notable applications

of WSN are in the field of military, environmental,

agriculture, health, and ecology [1].

II. CHALLANGES AND RESEARCH ISSUES IN WSNWSN is a multi-hop network, so the broadcast and

reception course is not at all times ended straightforwardly

from resource node to sink node, the job is done by similar

transitional nodes [2]. This development is prolonging until

sense information reaches the base station. To keep this

contact, WSN must have an energy skilled routing protocol

to maintain connectivity contained by the network [4-5]. A

superior Medium Access Control (MAC) protocol is

capable of keep away from collision and interference

between nodes [6]. Within an uncontrolled environment to

avoid malicious attack there should be maintain

confidentiality, integrity and authentications [7].

To enhance the coverage problem sensor should be

deploy in fine method [8]. These are the investigate area

otherwise issue which directly bang on the network lifetime, connectivity, security and network coverage.

III. RELATED WORK

The routing protocols that have been used in the wireless

Ad hoc network were also used in WSN [9-10]. The

performance evaluation of WSN was carried out to find the

packet dropped, packet delay and packet delivery ratio

using simulator NS.2.26 [11]. Comparison between the

Routing with error reporting protocol(RERP) and Ad hoc

on demand distance vector (AODV) for packet

transmission, energy Consumption and fault tolerance wasanalyzed using NS2.34 simulator [12]. The performance

analysis of the dynamic mobile wireless sensor networks

(DMWSN) has been reported using Dynamic Source

Routing (DSR), AODV and DREAM [13]. Furthermore,

the energy consumption and packet delivery ratio of

AODV and HYBRID ADHOC ON DEMAND

DISTANCE VECTOR (HAODV) has been reported using

NS 2.34 network simulator [14]. Using Qualnet, the no of

packets received and sends and the throughput of AODV

routing protocol was determined [15]. In the present

research, the same simulator Qualnet is used to compare

AODV and DSR with different path loss model.

IV. PERFORMANCE AND BEHAVOIR

The simulation environment is carried out by four

scenarios on Quannet Graphical User Interface (GUI).The

four scenarios are divided into two cases. For first case

performance is carried out with two dissimilar Scenarios

through AODV in addition to Two Ray Path Loss Model in

opposition to DSR plus Free Space Path Loss Model.

While in favor of Second Case the performance carried out

with AODV along with Free Space Path loss model against

DSR and Two Ray Path Loss Model. For different scenario

different numbers of sensor nodes are taken. The details of

the parameter, that are used in the above scenario is

mention the table-I.These sensor nodes are put in a

1500*1500 meter plane surface. For evaluating the effect of

QoS variation on different protocol and path loss model are

analyze. The protocol evaluations are based on the

simulation using Qualnet 5.0.2

model. Second scenario is carried out with 15 sensor nodes.

From the simulation it has been observed that

transmitted packet is same for both scenarios. The packet

receive at the receiver end is different for AODV and DSR,

from the graph it is observed that AODV with scenario at

location node-7, node-9 and node-14 only transmitted

packet there is no received of any packet which is the

primary requirement of the network. The Packet dropped is

extra when use DSR plus Free Space path loss modelCompare to AODV plus Two Ray so for most of the time

AODV plus Two Ray Path loss model perform better

compare to DSR plus Free Space path loss model.

Case-2:

The performance is carried out with comparison between

two scenarios. In the first scenario done with 15 sensor

nodes with mobility is static along with the routing protocol

AODV plus Free Space path loss model. Second scenario is

done with 14 static nodes. The different is at this time

routing protocol DSR plus Two Ray path loss model restof parameters are same as declare in the table-I.

From the simulation it was observed that the transmitted

packet is same for both scenarios. The packet receive at the

receiver end is different for AODV and DSR, from the

graph it was observed DSR use scenario at position node-

received of any packet which is the primary requirement of

the network. The Packet dropped is more when are usingAODV plus Free Space path loss model Compare to DSR

plus Two Ray.

VI.CONCLUSION

The performance and behavior of static sensor nodes of

WSN is done using Qualnet 5.0.2. The experiment is base

on the comparison between two cases, for first case it has

been done using AODV plus Two Ray path loss model

with DSR plus Free Space path loss model. The second

case is done using AODV plus Free Space model and DSR

plus Two Ray path loss model. It has been observed fromthe above simulation that most of time when path loss

model is Two Ray the network Perform Better.
