The Definition of WSN

consist of large amount of sensor nodes

Multi-hop, self-organize

wireless communication

cooperative sensing, collection, process

Send to observe.

A wireless sensor network (WSN) is a wireless network consisting of

spatially distributed autonomous devices using sensors to monitor physical or

environmental conditions. A WSN system incorporates a gateway that

provides wireless connectivity back to the wired world and distributed nodes

OBJECTIVE

Understand about the basics of Ad hoc network, various standards and different

routing protocols including proactive and reactive

Analyze the trace file and they can check the entire time duration of the simulation

Determine the best possible path in terms of minimizing the number of hops (path

length), delay, packet loss, cost

Energy-aware routing increase the lifetime of the network.

Minimum cost forwarding.

The difference between WSN and Ad hoc

The number of nodes

Sensor nodes are densely deployed

Sensor nodes are prone to failures

The topology of a sensor network changes very frequently

WSN broadcast but ad hoc point-to point

Sensor node are limited in power computation capacities and memory

Sensor nodes may not have global identification

What is network simulator

•A network simulator is software that predicts the behavior of a computer network. Since communication Networks have become too complex for traditional analytical methods to provide an accurate understanding of system behavior network simulator are used.

•In simulators, the computer network is typically modeled with devices, links, applications etc. and the performance is analysed. Simulators typically come with support for the most popular technologies and networks in use today.

Flooding

•A classical mechanisms to relay data in sensor

networks without the need for any routing

algorithms and topology maintenance.

•Drawbacks:•Implosion

•Overlap

•Resource blindness

Page 9: Pawan( WSN routing Protocol)

Gossiping

•A slightly enhanced version of flooding where the

receiving node sends the packet to a randomly selected

neighbor which picks another neighbor to forward the

packet to and so on.

Advantage: avoid the implosion

Drawback: Transmission delay

Routing Challenges and Design Issues

in WSNsThe design of routing protocols in WSNs is influenced by many

challenging factors. These factors must be overcome before efficient

communication can be achieved in WSNs.Node deploymentEnergy considerationsData delivery model Node/link heterogeneityFault toleranceScalabilityNetwork dynamics Transmission media Connectivity Quality of service

ADVANTAGES

WSN offers several advantages over traditional circuit switching

networks. These includes-

Avoids a lot of wiring

Can accommodate new devices at any time

Flexible to go through physical partitions

It can be accessed through a centralized monitor

FUTURE SCOPE

More research work needs to be done in future.

Needs to be implemented in a wireless sensor network with mobile

nodes.

The effects of very large node densities need to be investigated.

The feasibility of using the clustering technique and data aggregation

needs to be tested in the same wireless sensor network.
