【摘要】 无线传感器网中,由于节点具有有限的传输范围及电池能量,所以最大化网络的生命周期受到越来越多的关注。研究邻域传感器网络,其定义为不同授权许可下,且物理上位于同一个区域或互相接近的多无线传感器网络。构造一个线性规划框架用于描述邻域传感器之间的协作,并且与非协作网络进行比较。研究表明,如果邻域传感器网络彼此协作处理中继数据包,与非协作情况相比,网络的寿命得到延长,并且协作降低了由此引起分离分区的概率。更多还原

【Abstract】 As the node in wireless sensor network has limit transmission range and battery energy,therefore to maximise the lifecycle of network attracts increasing concerns. In this paper we study the neighbourhood sensor networks which are defined as the multiple wireless sensornetworks under different authorised permissions but located physically in the same area or close to each other. We construct a linear programming framework to characterise the cooperation between neighbourhood sensors in comparison to non-cooperation networks. The study shows that if the neighbourhood sensor networks cooperate with each other in processing the relay data packets,then compared with the situationof non-cooperation,it brings the advantages as such as prolonging the lifetime of networks and reducing the probability of disjoint partitionscaused.更多还原
