Abstract

Wireless sensor networks (WSNs) are short range personal communication networks that are widely used in environmental monitoring and other applications such as military and healthcare. A WSN is formed of a number of sensor nodes which are normally battery operated and have limited computational capability. The sensor nodes collaboratively collect the required data and disseminate the data from the source to the sink. Direct data transmission from the nodes to the sink consumes high amount of energy thus reducing the network lifetime. In addition, in a dense sensor network, the possibility of the nodes to have an overlapped sensing area is very high. If every node sends its data, the sink will receive the same data yielding to inefficient energy consumption. To solve the problem, topology control is used to improve the performance in term of network lifetime and energy consumption. Topology control consists of two phases which are topology construction and topology maintenance. The objective of this project is to evaluate the performance of A3 Topology Control protocol in WSNs. The simulation works are executed by using a WSN simulator called Atarraya. The run based of the selected parameter. By using CDS rule K as the reference topology expected result will get A3 is better than CDS rule K.
