Recent advances in microelectronics have made feasible the deployment of sensor networks for a variety of monitoring and surveillance tasks. The severe energy constraints met in such networks make imperative the design of energy efficient protocols for communication. One method is to use Multiple-Input Multiple-Output (MIMO) links. The multiple antennas allow MIMO systems to perform pre coding (multi-layer beam forming), diversity coding (space-time coding), and spatial multiplexing. In this paper, we propose a Energy balancing intelligent clustering protocol based MIMO scheme which is an improvement of LEACH based MIMO scheme. Proposed scheme aims at balancing the energy consumption in every cluster, enables multihop transmissions among the clusters by incorporating cooperative MIMO scheme through the selection of cooperative sending and receiving nodes and prolonging the network lifetime. A fitness function is used to balance the energy consumption in every cluster according to the residual energy and positions of nodes. In every round the node called auxiliary cluster-head calculates the position of the cluster head using Bacterial Foraging Optimization Algorithm (BFOA).
