For mobile ad hoc network (MANET) applications with sensor devices such as disaster recovery, it is necessary to provide streaming services for surveillance activities. For such uses, we propose a Spatial Resource Allocation (SRA) based Quality of Service (QoS) model for MANET integrated with sensors. Borrowing ideas from differentiated services (DiffServ), our protocol adapts to variations in terms of spatial properties such as bandwidth, interference and capacity. SRA model selects a single or multiple resource allocating (allocator) nodes to perform resource allocation in the forwarding path. The promising behaviour exhibited by SRA is its simplicity and lightweight nature. This makes it suitable for sensor networks. It differs from existing schemes, through dynamic priority assignment by nodes, in forwarding path rather than source node, reflecting network behaviour in the forwarding path. The priority assignment is done based on hop count. Extensive simulation using ns-2 is performed to evaluate the performance of the model. It has been found that the energy saving introduced is about 20% and the reduction in number of retransmissions is about 30%. This scheme works over the existing routing protocol, requiring no modification to it.
