A new group mobility model for mobile adhoc network based on unified relationship matrix

Most of the mobile Adhoc network protocols are validated by simulation environment. The validation is meaningful when they use realistic movement mobility models, which directly impacts the performance of the protocols. Once the nodes have been initially distributed, the mobility model dictates the movement of the nodes within the network. If this movement is unrealistic, the simulation results obtained may not correctly reflect the true performance of the protocols. The majority of existing mobility models for adhoc networks do not provide realistic movement. Mobility model based on social network theory predicts the node movements more realistic. Our paper reinforces the model by using Unified Relationship Matrix, which improves the movements of groups. Unified Relationship Matrix helps to represent the relationships of inter and intra type of nodes. Movements of nodes and groups are evaluated by keeping a small distance between each node and maintaining each group velocity, direction and movements. Group velocity is calculated by inter relationship matrix and cumulative nodes velocity. Group movements are calculated and directed by Unified Relationship Matrix.
