Infrastructure-Less Wireless Networks Employ Reactive Routing with Knapsack-Based Buffer Management

Abstract

Wireless infrastructure-less networks provide network resources independent of location. These networks are mobile, resource heterogeneous, peer-to-peer, self-forming, and adaptable. Health management, military, and disaster aid use such networks for reliable communication. These networks use routing to connect source and destination nodes and forward data packets. Network nodes' buffer sizes hinder efficient routing. We present a buffer-aware route-finding system that optimises nodes' packet processing based on their residual buffer size using the knapsack algorithm. Our buffer overflow-prevention method improves network performance. Using the NS-2 simulator, the suggested mechanism reduces packet loss, improving network performance. Our work proposes an effective routing protocol for wireless infrastructure-less networks that takes into account nodes' restricted buffer sizes. The proposed system could be used where efficient and reliable communication is needed.
