Medium Access Control Protocols for Wireless Sensor Networks: A Study

Abstract

Wireless Sensor Networks (WSN) is an interconnection of different sensor nodes deployed over geographical areas to communicate with each other and guiding the information of target to base station via sensor and sink nodes [1]. For exploiting the prospective benefits of WSNs requires a high-level of self-organization into a multi-hop wireless network, proficiency and coordination among the sensors to accomplish the jobs required to upkeep the underlying application. For multi-hop wireless network to work requires neighboring sensor nodes to communicate with each other through air in form of electromagnetic signal. All sensor nodes must share this common transmission medium in aunbiased and rational manner. This paper discusses the overview and fundamental design issue of Medium Access Protocol used in shared medium.
