Executive Summary

Wireless MIMO (Multiple Input Multiple Output) mesh networks recently emerge as a flexible, low-cost and multi-functional networking platform with wired infrastructure connected to the Internet. Mesh routers are equipped with multiple radio transceivers that can work simultaneously. This MIMO feature greatly improves data throughput of mesh routers. A critical issue in MIMO mesh networks is to maintain network coverage and routing for a long lifetime with high energy efficiency. As more and more outdoor applications require long-lasting, high energy efficient and continuously-working mesh networks with battery-powered mesh routers, it is important to maximize the performance of mesh networks from a battery aware point of view.
