无线传感网中的汇聚传输模式使得靠近汇聚点的节点承担了较多的数据转发业务，导致这些节点能量很快耗尽，造成网络节点负载分布不均衡。针对这种汇聚传输问题，结合规则拓扑结构的对称性和预知性，提出基于 Square Grid 规则拓扑结构中分析典型源路由策略，设计一种计算路由节点负载分布的转发指数，并依据该转发指数分析各路由策略负载性能的方法。通过 Math-ematica 绘制各路由节点负载分布图并对比各路由策略的转发指数，实验结果验证了 Balancing Forwarding 路由策略的节点具有较均衡的负载分布。该方法能有效地应用于评价路由策略的优劣。

Gathering transmission pattern in WSN causes the nodes close to the aggregation node bearing more data forwarding jobs and this leads the quick power exhaustion of those nodes and results in the imbalance distribution of the nodes load in networks.Considering this gathering transmission problem,in combination with the symmetry and foreseeability of the regular topology structure,we propose a Square Grid rule-based typical source routing strategies analyses in topology structure,and design a method which computes the forwarding index of load distribution of routing nodes,and analyses according to the forwarding index the load performance of each routing strategy.Through Mathematica we plot the load distribution graph of routing nodes and compare the forwarding indexes of routing strategies.Experimental result confirms that the Balancing Forwarding routing strategy has rather balanced load distribution.The conclusion derived is that this method can be effectively applied to evaluating the pros and cons of routing strategies.
