Sensor Networks: MAC Protocols

Sensor networks are autonomous networks that consist of up to thousands of nodes performing some specific task such as sensing environmental events. The devices are highly constrained: The devices have for example poor computing capabilities and battery resources. The nodes need to communicate with other nodes to convey the sensed information to a device collecting the data. When designing MAC protocols for sensor networks, the constraints of sensor networks need to be taken into account. In this paper, short description of sensor networks is presented followed by descriptions of some MAC protocols.
