Resource Allocation in Load-Constrained MultihopWireless Networks
The fact that the wireless spectrum is a scarce resource motivates one to investigate how to use wireless resources effectively. A wireless network has two kinds of network entities - users and nodes, where a user maintains a session (multipath flow) from a source node to a destination node, and uses intermediate nodes to forward the packets. In this paper, the authors study the influence of network entity load constraints on network resource allocation. They focus on the problem of allocating network resources to optimize the total utility of multiple users in a wireless network, taking into account four resource and social requirements: user QoS rate constraints, node max load constraints, node load balance constraints, and node-user load constraints.
