Wireless Mesh networking Protocol for sustained throughput in edge computing

It is critical to provide sustained data throughput in edge computing, where several sensor devices generate information that needs to be fused and used for decision making in e.g., disaster incident scenes. To this end, we compare the effectiveness of two protocols, Hybrid Wireless Mesh Protocol (HWMP) and Greedy Perimeter Stateless Routing (GPSR), based upon their ability to stream data in a mesh network. We model the two protocols using three topologies consisting of a sender, receiver and multiple Mesh Points to relay the data. We perform experiments varying the density, scale and failure rates of the topology. Finally, we evaluate the effectiveness of both protocols by comparing the total throughput from sender to receiver in each experiment. We show that geographic routing algorithms such as GPSR, given their potential for statelessness, can be more effective in delivering sustained data throughput than the 802.11s standard HWMP in high failure and large scale topology cases.
