This paper introduces a new IEEE standard, IEEE 802.15.5,which provides mesh capability for wireless personal area network (WPAN) devices. The standard provides an architectural framework enabling WPAN devices to promote interoperable, stable, and scalable wireless mesh topologies. It is composed of two parts: low-rate WPAN mesh and high-rate WPAN mesh. In this paper, we present only low-rate WPAN...
Because of the instability of link quality, traditional network routing protocols, which are mainly based on the condition of "Best Path", can not work very well over wireless mesh networks. Forwarding packets along the "Best Path" may also induce load imbalance among nodes. This paper presents a novel routing protocol named HPRP (Hierarchical Probabilistic Routing Protocol) for...
Collecting data from source sensor nodes to designated sinks is a common and challenging task in a wide spectrum of sensor network applications, ranging from animal monitoring to security surveillance. A number of approaches exploiting sink mobility have been proposed in recent years: some are proactive, in that sensor nodes push their readings to storage nodes from where they are collected by roaming...
