XLCI Protocol for High QoS in Industrial Wireless Network

Abstract

In this paper, we design a protocol to communicate data reliably in harsh environments. Robust data transmission with high accuracy is imperative in industrial wireless networks. The communication over a radio link in such environment gets affected by noisy surroundings. In order to maintain the high quality of services in these networks, cooperation and adaptability at a cross layer are introduced in proposed scheme. The collaborative coding used in proposed protocol; combine the data packets of network sources to improve channel capacity. This reduces the routing overheads and enhances the network gains along with the introduction of minimum delay. The performance of the network is evaluated using parameters such as throughput, reliability, channel utilization, energy, and latency for different network sizes. Results of the proposed protocol are observed and compared with the industrial wireless communication standard Wireless HART (WHART). In rest of the paper, the proposed ‘Cross Layer Cooperative Industrial Protocol’ will be termed as “XLCI Protocol”. Results shows that XLCI protocol improves the network throughput by 53%, reliability by 40%, channel capacity by 40%, also energy consumption is reduced by 70% and latency is improved by 46%, as compared to WHART.
