Enhancing Network Life-Time of Wireless Sensor Networks through Itinerary Definition and Mobile Agents for Routing among Sensor Nodes

Mobile Agents-Based Wireless Sensor Networks (WSNs) offer a good alternative to the conventional client/server network model. Mobile Agents (MA) is a computational code that is injected inside a packet that migrates among sensor nodes for data collection. The itinerary planning for MA is the most challenging task during mobile agents migration in wireless sensor networks. In this study, a routing itinerary scheme for multi-mobile agent itinerary planning for energy efficiency in wireless sensor networks by constructing the spanning tree of wireless sensor nodes is formulated. In the scheme, the sensor network is divided into several clusters. The cluster formation of the network consist of n sensor nodes divided into m disjoint clusters and the sequence of the collected data is combined with a fusion factor. The itinerary paths of the MA is defined using minimum spanning tree. It is assumed that the sink node is equipped with all the information about the SNs so that the sink can calculate the weights between cluster heads. The proposed Energy-Aware Mobile Agent Based (EAMB) model performed better than Least Energy Adaptive Clustering Hierarchy (LEACH), Local Closest First (LCF) and Global Closest First (GCF).
