This paper proposes a new heterogeneous multi-hop cellular IP (MCIP) network that integrates multi-hop communication with cellular IP. MCIP increases the coverage of the wireless network and improves the network robustness against adverse propagation phenomena by supporting communication in dead zones and areas with poor radio coverage. MCIP includes three components: location management, connection...
Wireless LAN-to-cellular vertical handoff involves time consuming procedures that may significantly disrupt real-time communication. This situation is compounded by the fact that WLAN coverage may sometimes be lost very abruptly and without warning. In this paper we propose and investigate the use of a vertical handoff support node (VHSN), which is attached locally to the wired LAN hotspot infrastructure...
In this paper, we propose guided broadcast algorithms (GB) - a family of distributed broadcast algorithms for wireless sensor networks (WSNs). GB is based on the recently proposed self-organizing redundancy cellular architecture (SoRCA) for WSNs. It utilizes spatial diversity to cover the sensor nodes in the WSN for a tunable number of times to ensure that at least n portion, a parameter specified...
