Using proxy servers to cache and shape network traffic can significantly improve the energy efficiency of the participating mobile clients. In this paper, we analyze the implications of hosting a BitTorrent proxy on a broadband router, which pushes the content to a mobile phone over wireless radio (WLAN or 3G). The amount of memory in a router is limited and therefore our interest is on how to use...
It is expected that Peer-to-Peer (P2P) services will co-exist with the client-server based services such as IMS. Mobile users may subscribe to the traditional wireless cellular services while participating in P2P overlay networks. In this paper, a method is proposed to reduce the signaling overhead in a mobile P2P system. With the help of the underlying infrastructure, a mobile device in the P2P overlay...
In a satellite network, a centralized payload router peers with hundreds, to potentially thousands of terminals that serve as gateways for highly mobile user networks. These terminals and user networks generate significant amounts of control plane traffic when exchanging routing information that must be processed by the payload. Many factors influence this control traffic load, including neighbor...
To improve the local mobility performance of a wireless network, we present a new framework, namely Efficient Framework for Local Mobility (EFLoM). In EFLoM, we introduce three entities: Local Anchor Router (LAR), Wireless Access Gateway (WAG) and Mobile Node (MN). LAR is a router that is in charge of MN's IP mobility management. It keeps track of MN's movement, and delivers the MN's packets to its...
