Analysis and simulation of Network Inaccessibility in LR-WPAN using NS2

Abstract

Wireless technology has many challenges for predictability and time-bounded communications over the temporary partition, called inaccessibility. Network inaccessibility is a temporal issue derived by the Medium Access Control sublayer in presence of fault affecting the communication services. Reducing the network inaccessibility in IEEE 802.15.4 wireless communications is most challenging step to enhance network communication in terms of dependability, timeliness and predictability, which enforce real-time operation. In beacon-enabled and non-beacon enabled mode, link failure self- recovery, low duty cycle, association to shape up the entire network to work efficiently has been analysed. Simulation result shows the network performance in terms of Quality of Service metrics, association, orphaning and recovery for different topologies.
