Performance Evaluation of A Peer-to-peer Wireless Ad-hoc Network

Abstract

This paper has investigated the performance of a peer-to-peer wireless Adhoc network in an indoor and outdoor environment. The objective is to assess the network performance using metrics such as throughput, packet loss, packet latency and packet delivery ratio (PDR). In the investigation, two measurement locations were chosen; Location 1 (an indoor) and Location 2 (an outdoor). At each of these locations, data packets of 28.6MB was deployed in successions across the network and the responses were observed at the client’s node in real-time mode. Results of the experimentations at both locations show packet losses across the network which is more pronounced at Location 2 (outdoor). Also, higher packet latency was recorded at Location 2 compared to Location 1. The investigation results were compared with similar research works to validate the accuracy of our work. It was thus inferred that between the two locations, the outdoor environment shows a low level of reliability in terms of network performance. A knowledge of these performance metrics is essential for network administrators, engineers and researchers for proper network planning, design and deployment.
