Abstract
The growth of smart phone technology have resulted in increased number of multimedia application which requires low latency service delivery and coverage which the existing wireless technology could not handle due to power limitation imposed by Wireless Local Area Network (WLAN) regulatory body. To address this wireless mesh networks (WMNs) was standardized by task group S to support multichip based communication. Reducing packet delivery latency in existing multichip WMN is one of key issues that need to be addressed. The existing methodology induces high data delivery latency due to inability to address the hidden and exposed node problem in multichip WMN environment. Many approaches have been developed to optimize the Medium Access Control (MAC), hidden node and exposed node detection algorithm in recent time to better utilize slot and reduce latency. The existing method adopts contention based method to address the collision caused by the hidden node problems which result in improper utilization of slot, which result in bandwidth wastages. Node classification technique for reutilizing slot will aid in improving network performance by reducing latency. As it is seen the latency plays a significant part in improving the performance overall throughput of a network. This work proposes an efficient device classification based MAC scheduler by adopting a cross layer design to reduce the data delivery latency. The experiments are conducted to evaluate mean network latency and data delivery latency by varying depth of tree for varied network size and density. The outcome shows that the proposed approach perform better than existing CSMA/OCA in term of network data delivery latency.
