An Energy-Efficient Routing Protocol for wireless sensor networks through nonlinear optimization

Wireless sensor networks (WSN) are an important new technology for remote monitoring. However, an important feature that distinguishes the WSNs from traditional monitoring systems is their energy constraints. Unlike traditional remote monitoring systems, the energy management policy of sensor node needs to take into consideration. Nodes in a multi-hop WSN need to transmit their own information and to relay each other´s information to a gateway, and there are usually multiple available paths between a node and the gateway. In this paper we proposed an algorithms that minimizing the energy per bit, or equivalently, by maximizing the amount of information delivered to the BS under certain energy constraints. The simulations are adopted for mining applications scenario. The results show that the proposed algorithm can reduce the consumed energy of the sensor nodes.
