摘要
无线传感器网络通常由大量微型传感器节点组成,可以在各种环境下收集数据,它通过携带能量有限的电池来供应能量,通常部署在区域环境复杂,甚至工作人员不能到达的场合,所以,传感器网络节点往往能量有限,而且不能更换,如何高效使用能量是传感器网络面临的首要挑战。MAC协议处于传感器网络协议的底层,对传感器网络的性能有很大影响。文中讨论了无线传感器网络中的一种自组织无线传感器网络协议—SMACS协议的基本思想,研究了造成节点能量浪费的主要原因,并提供了一种新的更节能的SMACS协议超帧的改进算法。
Wireless sensor network usually consists of a large number of tiny sensor nodes, it can collect data in a variety of environment, it is limited by the battery to carry the energy to supply energy, usually deployed in a complex regional environment, and even the staff can not reach an occasion. Therefore, sensor networks nodes have limited capacity, and can not be replaced, how the efficient use of energy is the primary challenge faced by sensor networks. MAC protocol is the bottom of sensor network protocol for sensor network have a great impact on performance. The paper discusses wireless sensor network in a self-organizing wireless sensor network protocol--the basic idea of SMACS protocol, to study the main reasons for energy waste caused by the nodes, and provides a new, more energy efficient SMACS agreement improved algorithm for super-frame.
