A POWER EFFICIENT ROUTING SCHEME IN WSN: IMPLEMENTING GREEN NETWORKS WITH EAMMH PROTOCOL

Abstract

Wireless Sensor Networks consist of small nodes with sensing and computation, communication
capabilities. Wireless network are highly dependent on specific application and are constrained by energy, storage
capacity and power. To increase the lifetime of networks, energy awareness is essential consideration if we analyze
routing protocols. Routing protocols of sensor networks are responsible for maintaining the routes in the network.
Wireless sensor networks are generally battery limited deployed in remote and crucial areas where continuous
monitoring is essential. One of the main design issues for such a network is conservation of the energy available in
each sensor node. Increasing network lifetime is important in wireless sensor networks. Wireless distributed sensor
network consists of randomly deployed wireless sensors having low energy assets. These networks can be used for
monitoring in a variety of environments. Major problem of these networks is energy constraint and lifetime, so, to
overcome these problems different routing protocols and clustering techniques have been introduced. The proposed
scheme describes a new way to select the Cluster head. Analysis shows that the extended version or enhanced
LEACH protocol balances the energy expense, saves the node energy and hence prolongs the lifetime of the sensor
network. Also a comparison between LEACH, proposed scheme (extended version) and Energy aware multi-hop
multi-path hierarchy protocol (EAMMH) is presented.
