Modeling for Congestion Prediction in Wireless Sensor Network Using Traffic Demands Analysis
نویسنده
چکیده
Wireless sensor network is an event based system with several sensor nodes. Reliable data transfer at the sink is based on collective information provided by sensor nodes. However, due to the unreliable wireless communication nature, it is hard to guarantee the end-to-end reliability and timeliness. Hence, we propose a congestion prediction model that ensures the reliable delivery of packets to a base station, and that minimizes packet dropping within sensor network. This model includes a node traffic and path traffic prediction that occur network congestion. Simulation is demonstrated using ns-2 and matlab. Key-Words: WSN, Congestion Prediction, Traffic Demands Analysis, Node Traffic, Path Traffic, Traffic Modeling

Wireless Sensor Networks (WSNs) offer inherent packet redundancy since each point within the network area is covered by more than one sensor node. This phenomenon, which is known as sensors co-coverage, is used in this paper to detect unauthenticated events. Unauthenticated event broadcasting in a WSN imposes network congestion, worsens the packet loss rate, and increases the network energy con...
