基于能量均衡的最大化覆盖目标算法
Energy-Balance-Based Maximizing Network Lifetime Algorithm in Wireless Sensor Networks
摘要
Abstract
Target coverage problem is one of the important problems in wireless sensor network in which each target should be covered by at least one sensor. Therefore,EMNL( Energy-balance-based Maximizing Network Lifetime) al-gorithm is proposed. In EMNL,All the sensors are organized into different groups called sensor cover in such a way that each cover can monitor all the targets for a fixed duration. By keeping one sensor cover active at a time while others in sleep mode,sensors batteries can be used in efficient way. This helps in prolonging the network lifetime. EMNL algorithm proposes a new energy-efficient heuristic to schedule the sensors in different non-disjoint sensor covers which helps to maximize network lifetime. Finally,we construct simulation and analyze performance of EMNL algorithm. The simulation results show that EMNL algorithm outperforms than other algorithm in term of coverage ra-tio,and network lifetime.关键词
