In this paper, we investigate the problem of grouping the sensor nodes into clusters to enhance the overall scalability of the network. A selected set of nodes, known as gateway nodes, will act as cluster-heads for each cluster and the objective is to balance the load among these gateways. Load balanced clustering increases system stability and improves the(More)
Wireless sensor networks have been receiving increasing attention in recent years due to their potential applications in the establishment of dynamic communications for emergency/rescue operations, disaster relief efforts, and military networks. In this paper, we investigate the problem of grouping the sensor nodes into clusters to enhance the overall(More)
In this paper, we proposed a routing and resource reservation protocol that support both unicasting and multicasting for mobile ad hoc network (MANET). Unlike wired network where the network topology is rather static, the topology of a MANET changes regularly depending on the mobility of network nodes. Hence, integrating the resource reservation protocol(More)
Peer-to-peer (P2P) networks establish loosely coupled application-level overlays on top of the Internet to facilitate efficient sharing of resources. They can be roughly classified as either structured or unstructured networks. Without stringent constraints over the network topology, unstructured P2P networks can be constructed very efficiently and are(More)
