In a wireless sensor network, aggregation is either done to avoid the redundant transmissions. In service provisioning, the control packets sent for service advertisement and discovery contribute significantly to the network traffic. In this paper, it is proposed to aggregate the similar control packets sent from different sources to a common destination along with minimum spanning tree, which is constructed for service provisioning. The mobile agent migration schemes used in the literature have got overhead in finding the migration path. Therefore, the proposed approach uses the spanning tree constructed for service discovery, as the migration path for the mobile agents. It is found from the investigation that the aggregation scheme has reduced average energy spent by 33%, control overhead by 12% and average discovery delay by 25%. Use of mobile agents has reduced the average discovery delay by 22%, control overhead by 19% and service discovery success ratio by 4%.

使用最小生成树增强服务发现协议的性能

在无线传感器网络中，要么进行聚合以避免冗余传输。在服务供应中，为服务通告和发现而发送的控制包对网络流量有很大贡献。在本文中，提出了将从不同源发送到公共目的地的相似控制数据包与最小生成树一起聚合的方法，该最小生成树用于服务提供。文献中使用的移动代理迁移方案在寻找迁移路径方面存在开销。因此，提出的方法将为服务发现而构建的生成树用作移动代理的迁移路径。从调查中发现，该聚合方案已将平均能源消耗减少了33％，控制开销减少了12％，平均发现延迟减少了25％。
