This article evaluates the performance of a quasi random deployment strategy for wireless sensor networks on the basis of the application invoked for tree based communication networks. The quasi random deployment strategy tries to combine the benefits of both random and deterministic approaches for effective coverage and connectivity. We adopt Halton sequence to generate the node placement co-ordinates and study the features and effects on the network traffic, the total carried load, the amount of delay incurred and the energy consumption under the IEEE 802.15.4 standard. Our analysis suggests the need to revisit currently used models of deployment in such networks. This paper also tries to suggest adoption of quasi based deployment on the basis of the simulation results. It shows that quasi random deployment strategy is better than deterministic deployment which is difficult to maintain and better than random deployment scheme that is expensive in terms of coverage, and network constraints.
