%X An Energy Efficient Cooperative Density Control Algorithm (EECDC) was proposed. EECDC is based on a new sensing model-Cooperative Sensing Model (CSM). According to CSM, serials of nonlinear constrained programming models were developed to find the optimal conditions for full coverage with minimal sensor nodes. Based on the findings, EECDC had been devised to select sensor nodes as close to optimal locations as possible to be the working nodes. Simulations show that EECDC outperforms OGDC algorithm in term of number of working nodes needed, and achieves almost the same coverage. As a result, it achieves higher energy efficiency and longer network lifetime.
