有限的能量、计算和通信资源使传感器网络中的协议设计复杂化，并且阻止了在其他网络中使用的许多技术的应用。对传感器节点成本的约束进一步限制了传感器网络可以利用的技术。尽管近年来备受关注，但研究人员尚未实现在这些约束下传感器网络部署的长期独立操作的目标。一个研究方向考虑执行通信功能所消耗的能量。介质访问协议对通信机制的影响最大，并且对收发器的利用率提供最直接的影响，收发器是大多数传感器节点中最大的能量消耗者。我们提出了一个讨论的媒体访问控制的概念，传感器网络和检查以前的无线媒体访问控制协议，以说明他们如何不匹配的要求和传感器网络的特点。然后，我们提出了几个协议最近在文献中提出的传感器网络。(c)2006 Elsevier B.V.保留所有权利。
Limited energy, computational, and communication resources complicate protocol design within sensor networks and prevent the application of many techniques used within other networks. Constraints on sensor node cost further restrict which technologies sensor networks may utilize. Despite much attention in recent years, researchers have yet to achieve the goal of long term, independent operation of sensor network deployments under these constraints. One research direction considers the energy expended performing communication functionality. Medium access protocols provide the greatest influence over communication mechanisms and provide the most direct influence over the utilization of the transceiver, the largest energy consumer in most sensor nodes. We present a discussion of medium access control concepts in relation to sensor networks and examine previous wireless medium access control protocols to illustrate how they do not match the requirements and characteristics of sensor networks. We then present several protocols recently proposed in the literature specifically for sensor networks. (c) 2006 Elsevier B.V. All rights reserved.
