Bandwidth management in wireless sensor networks

Wireless sensor networks are often used in monitoring and control applications, where software running on generalpurpose computers “pull” information from remote sensors and “push” actuations into the network. The sensors themselves form a multihop wireless network communicating with one or more sensor access points (SAPs) that interface between application software and the sensor network. This paper addresses the problem of managing wireless network bandwidth and improving network capacity in a sensor network deployed as a shared infrastructure, concurrently used by different applications. Our bandwidth management architecture incorporates three ideas: first, we develop a simple rule system that allows applications and the network administrator to specify how traffic generated by sensors should be treated by the sensor network. Each rule is a function that maps a sensor data type and generated value to a transmission rate and a traffic class. Second, we show how using mult...
