The Analysis And Research Of Enhanced Weighted Clustering Algrithm (EWCA)

Ad Hoc network has a promising prospect for civil and commercial use and in the field of military telecommunication, owing to its advantages of rapidness , flexibility, convenience, etc. Therefore, it has become a hot issue in recent study on network.The delaminating manage to the large scale Ad Hoc already has become a kind of trend and that the Clustering Algorithm is one of the key point. The search proposes a Enhanced Weighted Clustering Algorithm(EWCA) whose network performance is better than Weighted Clustering Algorithm(WCA). This article, by taking into the consideration of the network indexes involving the stability of cluster, electricity consumption of node, load balance and throughput of network,gives the depth analysis of Formula factors and their mutual relations of EWCA algorithm weights,discuss the operation of the network environment, the network of state-dependent factors and EWCA weights. Concludes :EWCA selects a cluster-header basing on the comparison of weight. A calculated weight relates to operating environment and a lot of factor of network. The method influences feasibility and quality of simulation directly, especially infecting the result of simulation decisively.After Considering complex external environment of node, digging factors of network, put forward a algorithm that calculates, sets and adjusts these weight by comparing-weight, efficient-weight and expecting-weight, so as to fit for all kinds of applicative environment. The algorithm not only guarantees the rational and effective weight , but also gives EWCA a warrant in calculation.
