Wireless sensor networks are emerging as a popular research issue and tool for many applications. However, nodes in a sensor network are severely constrained by energy, storage capacity and computing power. In this paper, we propose an integrated network environment (sensor and ad hoc network) with IEEE 802.15.4a, ultra-wideband (UWB) and two-tier data dissemination (TTDD) routing protocol. We wish that sensor network could support fast dynamic location-tracking, information gathering and response. And base station use theses information to compute an optimal path for ad hoc mobile devices to offer good QoS level and reliable data transmission according to different requests
