In this paper, we propose a bandwidth-efficient multicast mechanism for heterogeneous wireless networks. We reduce the bandwidth cost of an Internet Protocol (IP) multicast tree by...
WiFi interface is known to be a primary energy consumer in mobile devices, and idle listening (IL) is the dominant source of energy consumption in WiFi. Most existing protocols, s...
has to be relayed to nodes interested in those events. Moreover, nodes may also generate queries to find events they are interested in. Thus there is a need to route the informatio...
We consider the problem of finding "backbones" in multihop wireless networks. The backbone provides end-toend connectivity, allowing non-backbone nodes to save energy sin...

This paper proposes a solution to delivering multicast data reliably not only to/from fixed hosts but also to/from mobile hosts in combined fixed/mobile IP networks, particularl...
