Abstract:
Abstract—Meeting traffic demand and enforcing fairness are often times necessary but conflicting objectives for resource allocation in wireless networks. Due to the resource sharing nature of wireless networks, without a mechanism for enforcing fairness, simply assigning resources to meet traffic demand of some network flows can lead to resource starvation of other network flows. Balancing these two objectives is more complex multi-hop wireless networks, as the resource contention could be indirect. In this paper, an algorithm is introduced to allocate time slots in TDMA-based multi-hop wireless networks to achieve a designated a balance between meeting traffic demand and enforcing fairness. Numerical results show that the algorithm performs significantly better than other resource allocation algorithms. The introduced algorithm is well suited for distributed TDMA-based wireless networks, such as ECMA-368 based UWB networks.
