many nodes with antenna

WSN(Wireless Sensor Network)consists of many nodes with antenna which have the abilities of sensing, computing,and communicating. The nodes in shop 4u blog for shirts use the battery which can not be replaced or charged. So the energy efficiency is one of the main concerns that affect WSN performance in the routing algorithm designation.In this dissertation, the characteristic of WSN routing designation is introduced. Based on the chi hair straightener analysis of these chi pink dazzle characteristics, key technology and difficulty in WSN routing algorithm designation is illustrated. Next, some typical routing algorithms in WSN are introduced with the analysis of their pros and cons and classified according to three network structures. In former cheap polo shirts routing algorithms, two typical ralph lauren polo shirts algorithms bring great improvement to saving energy consumption, which are directional diffusion algorithm and cluster based algorithm. The basic Lacoste Polo Shirts idea of directional diffusion is that useful data gathered by node is transmitted to the base station in a fixed directon, while the basic idea of cluster based algorithm is to form clusters in the network based on nodes’location and energy status.
