Energy-Efficient Routing Protocol for Homogeneous WSN

Wireless sensor network is composed of large number of sensor nodes (SNs) and one or more sink nodes also called as base stations (BS) to which data is to be transmitted. These sensor nodes are associated with limited battery power and wireless communication which are deployed to collect useful information from the field. Gathering this sensed information in cost effective manner at base station is task of research.Earliest proposed techniques were directly transmitting data to base station which was further improved by collecting and aggregating the data in sensor network which increased network lifetime by a factor of 8, that is further improved by different proposed protocols.In this book a routing technique to collect and aggregate the data of sensor network and then to transmit it to base station is proposed which is based on MST generation among sensor nodes and partitioning the network into 3 areas (named tiers) based on the distance from base station and is implemented in c++, this proposed protocol is named as MSMTP (Minimum Spanning Multi Tier Protocol).The results obtained in this approach are about 1.4x improved as compared to PEGASIS protocol.
