Performance of Dynamic Priority Based Interference Aware Channel Allocation in Wireless Mesh Networks for Energy Conservation

Abstract

The Dynamic Wireless Mesh Network (DWMN) infrastructure is a pair or multiple dynamic nodes with networking capability to communicate with one another utilising Sink Nodes (SN). Due to its mobile nature, it is termed as Dynamic in nature. SN traverses over the predefined path over the Wireless Mesh Network. As the nodes engage into mobility, the neighbourhood table should be updated at a minimum rate of once every five seconds. The alarming fact in WMN is, Energy to transmit a bit is equivalent to computing hundreds of instructions at that instant. Hence there is a need to concentrate on energy dimension of DWMN. A node loses certain amount of energy while transmitting and receiving the packet, hence there is a minor decline in the initial energy of the node. The existing value of energy at a moment after transmitting and receiving the packet is coined as Residual Energy. The energy consumed by the node for transmitting and receiving the packet over the particular time frame is coined as Average Energy. Network Simulator v.2 tool has been utilised to simulate network creation with multiple mobile nodes for packet transmission or reception and packet drop conditions due to interference. Bandwidth Reservation (BR) for energy analysis is done by both Priority Based Interference Aware Bandwidth Reservation (PBIABR) and Interference Aware Bandwidth Reservation (IABR) for many flowing rates under dynamic scenario. Channel Priority plays a vital role to opt the channel which posses less interference for efficient bandwidth reservation for PBIABR. The opted channel will have the minimal channel interference effect. IABR posses the controllability character for data flow to establish end-to-end communication over Multi-Radio Multi-Channel (MRMC) - Wireless Mesh Network. This research paper focuses on deep analysis of Residual Energy (joule) compared with Interval (sec) and Average Energy (joule) compared with Interval (sec) under dynamic scenario for multiple flow rates by implementing PBIABR and IABR criteria.
