PROJECT TITLE :

A study on cluster lifetime in multi-hop Wireless Sensor Networks with cooperative MISO scheme

ABSTRACT:

As for cluster-primarily based wireless sensor networks (WSNs), cluster lifetime is one among the most vital subjects in recent researches. Besides reducing the energy consumptions of the clusters, it is necessary to form the clusters achieve equal lifetimes so that the whole network can survive longer. During this paper, we concentrate on the cluster lifetimes in multi-hop WSNs with cooperative multi-input single-output theme. With a simplified model of multi-hop WSNs, we modification the transmission schemes, the sizes and transmission distances of clusters to investigate their effects on the cluster lifetimes. Furthermore, linear and uniform knowledge aggregations are thought of in our model. Consequently, we tend to analyze the cluster lifetimes in different situations and discuss the requirements on the sizes and transmission distances of clusters for equal lifetimes.
