Coverage of wireless sensor networks (WSNs) is an important quality of service (QoS) metric and often the desired coverage is not attainable at the initial deployment, but node mobility can be used to improve the coverage by relocating sensor nodes. Unconstrained node mobility is considered infeasible based on the high locomotion cost that would nullify the advantage likely to be gained with the coverage improvement. Coverage improvement based on node mobility depends on many parameters including number of deployed nodes (static and mobile), proportion of mobile nodes, permissible distance the mobile nodes can move and the total distance nodes moved to attain certain coverage. The contribution of this paper is the investigation of the inter correlation of all these parameters for a grid-mesh architecture based on the grid quorum scheme. Having such information available prior to the practical deployment is a major advantage when designing the network, this can help improve both operation and cost.<br/
