无线传感器网络的应用越来越多,其安全问题备受关注。无线传感器网络面临着众多的安全威胁,而传感器节点能量的有限性导致了传统的安全机制很难满足需求。基于无线传感器网络自身的特性,并在此基础之上,针对LEACH算法的缺点考虑,对其进行了改进,进而提出了一种新的路由算法即SP算法。使用NS2模拟器通过仿真实验证明:与LEACH算法相比,最短路径路由协议更适合多层移动大规模无线传感器网络。
The application of wireless sensor networks is more and more, and its security issues have drawn much attention. Wireless sensor networks face many security threats, and the limited energy of sensor nodes leads to the traditional security mechanism is difficult to meet the demand. Based on the characteristics of WSN and based on this, aiming at the shortcomings of LEACH algorithm, this paper improves it, and then proposes a new routing algorithm called SP algorithm. Simulation results show that the shortest path routing protocol is more suitable for multi-layer mobile large-scale wireless sensor networks than the LEACH algorithm.
