Abstract
Cooperative diversity and selection diversity can be used to improve energy efficiency in wireless sensor networks. A diversity algorithm called the node selection-space-time block coding algorithm was developed to enable cooperation between a large number of nodes by using space time coding and by selecting the appropriate transmit and receive nodes. A generalized node selection algorithm was developed to relate the transmission energy consumption and the circuit energy consumption. The algorithm builds on the merits of various schemes- to develop an energy efficient scheme. Simulations show that the diversity algorithm and the node selection algorithm together effectively improve energy efficiency which will prolong the lifetime of wireless sensor networks.
