Assessment of fairness against quality of service parameters in wireless sensor networks

Abstract

Wireless sensor network (WSN) consists of sensor nodes to sense environmental or physical data and that will be communicated to sink through one hop or multi hop communication. These sensors are small, with limited processing and computing resources. These sensors can sense, measure, and gather information from the environment and transmit that data to the sink. All nodes in network are trying to send data to sink, in such scenario there is possibility of congestion. Congestion may reduce packet deliver ratio, throughput and network lifetime. Network lifetime is depends on energy consumption of each node in network. This paper introduced Adaptive Bandwidth Control (ABC) algorithm, which distribute bandwidth to the nodes as per distance from sink that. This reduces possibility of congestion and energy utilization of all nodes in a network is fair. Analysis is carried out with and without using this algorithm. Results show that energy as well as traffic fairness is improved.
