AODV and Cluster-Tree are usually used as route protocol in ZigBee network. In AODV, the broadcast mechanism makes energy run fast. Cluster-Tree protocol gets a long route path, which leads to high delay. This paper has done detailed research on these two protocols, and proposes a new address allocation scheme in order to make addresses carry with the topology information. In the process of route...
As WSN is a resource-constrained network, especially the limited energy, so it must maintain smaller router information and reduce the energy consumption as much as possible. This paper briefly introduces the wireless sensor network, and analysis the problems existed in LEACH routing protocol. Put forward the improved algorithm based on LEACH cluster head multi-hops algorithm, and under considering...
The Border Gateway Protocol (BGP), which is used to distribute routing information between autonomous systems, is an important component of the Internet's routing infrastructure. However, due to the lack of the mechanism the BGP is highly vulnerable to a variety of attacks. Many solutions have been proposed by some corporations or individual. But the current propositions either were difficult in operation,...
The wireless sensor network is a type of the wireless ad-hoc networks. It is composed of nodes with limited battery power. One of the most critical issues in designing wireless sensor networks is to minimize the energy consumption for longevity. In this paper, we first entirely analyzes state clustering protocol and LEACH routing protocol, then present a novel clustering routing protocol for wireless...
Nodes in wireless sensor network have limited battery power. In order to gain longer lifetime, this paper proposes a new energy efficient routing protocol by enhancing cluster election and transmission method. In this improvement, we elect clusters by using the nodespsila surplus energy. Then, the message in clusters can be delivered by multi-hop. Simulation shows that the scheme is better than the...
