Wireless networks have drawn a lot of attentions due to their rapid
development and their potential applications in various areas. In
addition to major benefits of wireless networks, challenges remain in
enabling this technology to have more utility for society. With
omni-directional antennas, signals from transmission nodes will be
received by nearby nodes. This will cause interference and thus will
dramatically reduce the throughput in the wireless network if routing
and scheduling are not carefully designed. Therefore, it is crucial to
avoid or reduce interference and increase throughput. Additionally,
nodes in wireless networks, especially sensors, are often powered by
batteries. This necessitates the development and improvement of energy
efficient protocols and battery life. Moreover, a number of other
challenging issues exist in wireless networks, such as compatibility
issues due to different standards, security issues in wireless networks
due to vulnerable and unprotected transmission media - air, and so on.
