Abstract
—a wireless sensor network is composed of tiny sensor
nodes. Each sensor node is battery operated and has limited
capacity for specific number of transmission rounds. In some
applications of sensor nodes, replacement of batteries is not
possible; this limitation cause energy constrain for wireless
sensor networks. Due to this restriction, energy efficient routing
protocols have gained vital importance. Many routing protocols
have been developed to improve the lifetime of wireless sensor
networks. In this paper one of the routing protocols, powerefficient gathering in sensor information systems (PEGASIS) is
modified as PEGASIS Improved Chain Formation (PICF) by
overcoming drawbacks in the existing protocol such as technique
of chain construction, selection of lead node and deletion of dead
nodes from the new chain formation. Simulation results of the
proposed protocol are compared with PEGASIS and one of its
variant PEGASIS Double Cluster Head (PDCH) to demonstrate
its outperformance.
