Routing can optimize network performance such as delivery ratio, delivery delay, and overhead. In
other words, routing determines the sequence of transmitting nodes and the number of packets
transmitted by each node. Transmitting nodes and the number of their transmissions influence the
generated interference.
Routing in wireless sensor networks (WSN) is very challenging due to the inherent characteristics that
distinguish these networks from other wireless networks like mobile ad hoc networks or cellular
networks. Routing protocols in WSN might differ depending on the application and network
architecture. In this assignment, students will investigate on two clustering based protocols, LowEnergy Adaptive Clustering Hierarchy (LEACH) and Power-Efficient GAthering in Sensor Information
System (PEGASIS) in Wirelessnetworks. LEACH and PEGASIS are clustering based protocol to collected
data from wireless network.
The students are required to submit a report including technical details on
? Routing mechanism
? How these protocols can be used to reduce energy consumption
? Advantages and limitations of using these protocols in WSNs
