Performance Improvement of Mobile Ad Hoc Network Using Particle Swarm Optimization
Mobile Ad hoc NETwork (MANET) is a self-organized network without depending on the fixed infrastructure. Improving security and reduction of misbehaving nodes in MANET is an important research domain. Misbehavior may seriously degrade the throughput, delivery ratio and delay of the MANET. IEEE 802.11 MAC needs to follow the communication procedure to get fair access to all participating nodes. However, some hosts may not follow the MAC protocol rules causing TimeOut Attack (TOA) of MAC frames to prevent from communication.
