Certain investigations on energy efficient approaches for routing protocols in wireless networks

Abstract

The wireless network is the network consisting of devices connected through radio frequency signals The wireless network can be broadly classified into ad hoc networks and wireless sensor networks These networks are commonly used when there is no fixed infrastructure and have its applications in surveillances military sector environmental monitoring and health care applications The resource limitations and the unexpected link failures in the network is a challenging factor while designing a routing protocol In this work different energy efficient approaches are introduced and incorporated in the design of energy efficient routing protocols for wireless network The three conventional routing protocols predominantly used in different applications are Destination Sequenced Distance Vector DSDV routing protocol Dynamic Source Routing DSR protocol and Ad hoc On Demand Distance Vector AODV routing protocol These protocols are implemented and the performance of these protocols is compared with standard metrics like Packet Delivery Rate PDR Average end to end delay Routing Overhead RO Normalized Routing Load NRL and Throughput The Dynamic Source Routing protocol is chosen for further analysis since it can be applied in scenario where minimum overhead is required The hop count based energy efficient routing protocol is the modification of DSR protocol where hop count and remaining energy of the nodes are used in routing decision The routing protocol chooses stable path for transmission of packet The protocol is compared with Energy Saving Dynamic Source Routing ESDSR protocol and results show that Hop count Based ESDSR HBESDSR protocol maximizes the life span of MANET and reduces the energy consumption and delay newline
