Power conservation is an issue of primary concern in wireless sensor networks. Since the nodes deployed have limited battery power higher transmit powers would lead to an earlier end of the nodes/network lifetime. The network deployed has to have a good connectivity level to ensure uniformity through out the network and avoid the circumstances leading to a very early lifetime end of some of the nodes...
An energy efficient cooperative MIMO selection scheme is proposed for uniform load distribution in cluster based wireless sensor networks. The intrinsic data flow direction in multi hop cluster based sensor networks causes uneven load distribution in the network. The transit clusters and the clusters near the base station carry more network traffic than the other clusters. Cooperative MIMO can artistically...
This paper presents an energy efficient selection of cooperative nodes with respect to their geographical location and the number of nodes participating in cooperative communications in wireless sensor networks. The cooperative communication in wireless sensor networks (WSN) gives us leverage to get the inherent advantages of its random node's locations and the direction of the data flow. Depending...
Power conservation is one of the primary issues to be taken care of in wireless sensor networks. Due to the limited battery life, the need to choose an appropriate transmit power becomes more important also to guarantee a maximal connectivity. Transmitting at the least possible power to prolong the network lifetime as a whole while also guaranteeing the best connectivity would be our main interest...
