Mobility in wireless sensor networks is an element which directly influences the network performance. Indeed, with an architecture based on the IP stack, a mobile node has to maintain connectivity with other sensors, also allowing connectivity to the Internet. Among IPv6 based protocols proposed for mobility management, we find Mobile IPv6 (MIPv6), Hierarchical Mobile IPv6 (HMIPv6) and Proxy Mobile...
More and more users subscribing to wireless broadband services are seeking to have access to both WLAN and UMTS networks. We study individually optimal user-network association in an integrated WLAN and UMTS hybrid cell. The association problem is formulated within a non-cooperative game framework. In the formulation, mobile arrivals are assumed to follow the Poisson process and each mobile considers...
Sink mobility has become an increasingly important requirement of various sensor network applications. Handling such mobile sink conditions brings new challenges to large-scale sensor networking. This investigation proposed a hybrid-structure routing protocol (HSRP) that combines the benefits of grid-based and cluster-based structures. Grid-based structure is designed to solve the cluster head selection...
