In this paper, the simulation and analysis are given to the network simulation tool OPNET network model of the LEACH protocol. The simulation results show that the improved routing algorithm I-LEACH (Improved-LEACH) is better than the original LEACH algorithm that extends the network life cycle, reducing the overall system energy consumption and enhancing the network scalability.
Routing is essential in P2P applications. Chord is a kind of structured P2P network, but its routing table can only cover half of the Chord ring. As long as target node is in the half ring which is not covered by the routing table, the target node must be found via not less than one medium node, namely, two hops. So, Chord is not very efficient. Therefore, a two-layer routing model for Chord(T-Chord)...
In order to solve the problem that the structure of P2P network's logical network and physical topology do not match at a large extent, information of resources' searching are time-consuming, we propose an improved P2P chord model which was based on the IP-LCO algorithm. The adoption of IPv6 addresses can solve the unmatched problem, and LCO algorithm can quickly location the resources' network node...
Most network operators have considered reducing Label Switched Routers (LSR) label spaces (i.e. the number of labels that can be used) as a means of simplifying management of underlaying Virtual Private Networks (VPNs) and, hence, reducing operational expenditure (OPEX). This letter discusses the problem of reducing the label spaces in Multiprotocol Label Switched (MPLS) networks using label merging...
