Description: The sensor nodes of a wireless grain depot
surveillance system are deployed in crystal grids, which provide
lot of valid position information. To avoid the energy
consumption unbalance of the single hop routing model adopted
by LEACH protocol, a novel hybrid routing model is proposed
in this paper. Multi-hop routing is introduced into the distant
field nodes through right angle transferring of approximate
equivalence consumption path. And the average energy
consumption is used as a threshold of selecting intermediate
transferring nodes to minimize total variance of node s energy
consumption, so that balance the whole network. Simulations
show that the hybrid model eliminates hot spots within cluster
and prolong the lifetime ofWSN. -The sensor nodes of a wireless grain depot

Description: In this work, performance evaluation of LEACH
and LEACH-C protocols based on NS2 is depicted, which
helps to reveal the regularity how performances of these
two routing protocols change with the sink locations. For a
more accurate description of this regularity, two novel
concepts are proposed, i.e., Sensor Node Distribution
Gravity and Distance Metric between sink and Gravity.
Simulation results show that a distance threshold area,
which is a key factor for choosing between LEACH and
LEACH-C protocols, can be achieved.

Description: 实现无线传感器网络leach协议。簇头随机分布在网络中，节点产生随机数，并判断是否大于阈值，如果大于阈值则作为簇头。每隔一定时间簇头选择一次。-Wireless sensor networks leach agreement. Cluster head randomly distributed in the network, the node generates a random number, and to determine whether greater than the threshold value, and if it is greater than the threshold as the cluster head. Intervals cluster head selection again.

Description: Abstract—In recent years, as the development of wireless sensor networks, people do some deep research on clusterbased protocol, most about the prolongation of the lifetime of WSN and decline of energy consumed by the sensors .This article analyses the cluster-heads generating algorithm among LEACH and presents improved approach that adjusting the nodes, Threshold function. When non cluster-heads choose optimal cluster-head, they consider comprehensive nodes' residual energy and distance to base-station, then compare their performance, the simulation results show that the new strategy of cluster-heads election achieve great advance in sensor and networks' life-time

Description: TEEN协议就是为反应式无线传感器网络而设计的路由策略，它具有实时性，可以对突发事件作出快速反应。TEEN采用与LEACH相同的多簇结构运行方式。不同的是，在簇的建立过程中，随着簇首节点的选定，簇首节点除了通过TDMA方法实现数据的调度，还向簇内成员广播有关数据的硬阀值和软阀值两个参数。(The TEEN protocol is a routing strategy designed for reactive wireless sensor networks. It is real-time and can respond quickly to unexpected events. TEEN uses the same multiple cluster structure as LEACH. The difference is, in the process of cluster establishment, with the selection of cluster head nodes, the cluster head nodes perform data scheduling in addition to the TDMA method, and also broadcast the two hard and soft threshold values of data to members in the cluster.)
