Aiming to eliminate the mismatch between structured peer-to-peer (P2P) network's logical topology and physical topology, which exists in these classic wired P2P protocols, the representative P2P protocol-Chord which is hardly suitable for wireless network is modified, and an approach of getting optimal node identifier (ID) to realize topology awareness is proposed by exploiting nodes' relative location...
To resolve the topology mismatch problem when applying peer-to-peer (P2P) file sharing over mobile ad hoc networks (MANETs), a cross-layer protocol is proposed by combining P2P file discovery with the route discovery process at the network layer. In this protocol, the functionality of conventional routing protocols is extended to identify the file discovery request, and P2P connections are established...
Chord is one of the best known lookup protocols for structured peer-to-peer (P2P) networks. Nodes in Chord can be viewed as being placed on a one-dimensional ring. In this paper, we present a novel concept of bi-dimensional P2P, in which all nodes are placed onto a square rather than a ring to enable the flexible configuration of ring(s). Diverse ring configuration schemes form a uniform protocol...
In this paper, we propose a distributed architecture to provide quality of service (QoS) for mobile Ad hoc networks (MANETs). The proposed architecture includes two major approaches: distributed control scheme and status-aware routing protocol, both of which are implemented in a fully distributed manner which do not need resources allocation or reservation at the intermediate nodes. Meanwhile, we...
In this paper, we propose a cross-layer approach for energy aware geographical routing in wireless sensor networks: Energy-aware geographical forwarding using adaptive sleeping(EnGFAS). We take (a) the characteristics of the applications, (b) route selection in the network layer, (c) scheduling in MAC layer, and (d) the acknowledge scheme in link layer into consideration. First, EnGFAS collects some...
