Chapter 1 is a general introduction. Chapter 2 presents the backbone of WSNs, the IEEE 802.15.4 protocol. The requirements for service-oriented sensor webs are presented in Chapter 3. Cross-layer design principles are described in Chapter 4. Grid co
This special issue aims to collect cutting-edge research achievements in this area. We solicited papers that present original and unpublished work on topics including, but not limited to, the following: physical layer models, for example, channel mo
Wireless and mobile Internet access has brought increased significance to the evolution of 3G packet-based communications and a vision of a future based on all-IP networking. To reduce handoff latency and signaling cost are two major issues. Certain
As a novel branch of widely used Wi-Fi technology, IEEE 802.11n has improved its maximum data rate to 600Mbps, which makes the transmission of high-definition video possible. Although many techniques have been adopted to maximize data rate for high d
Based on TDMA sleep scheduling scheme, by collecting cross-layer routing information and feedback information, according to the detection of routing information and neighbor information, the sleep slot and data transmitting slot are assigned orderly
