Comparison of Efficient Random Walk Strategies for Wireless Multi-Hop Networks

Free registration required

Executive Summary

Wireless multi-hop networks have drawn great attention from research and business communities since they suit well diverse application scenarios, such as environmental monitoring, military support in hostile environments and emergency applications. However, this challenging communication paradigm requires solutions able to fit specific requirements in terms of resource constrains, node mobility and quality of service. Random Walks (RWs) are probabilistic approaches to perform distributed operations, such as data search and retrieval. They are effective and have relatively small overhead compared to classic schemes, such as flooding.
