A Mobile-Gateway-Assisted Transmission Scheme for Wireless Sensor Network

摘要

Wireless sensor networks (WSNs) have been applied in many different areas. Data transmission quality of service (QoS) has become a hot research point for the WSN, especially for the emergency data. Many researchers focused on developing WSN access and routing algorithms for the transmission of QoS, but less research has been focused on the mobile user equipment (UE) acting as a gateway for WSN data transmission. In this chapter, we propose a UE-gateway-assisted adaptive transmission algorithm for the WSN, which designs a new signaling to select the UE-gateway as the access point. Simulation results show that the WSN system energy cost and data transmission delay can achieve a better system performance by using the adaptive scheme compared to the traditional scheme.
