Abstract

In this paper we present a consolidated scheduling and routing solution to the multimedia ad hoc network problem. We consider a generic ad hoc network with all kinds of heterogeneous devices. These devices are known to have different capabilities and capacities in terms of system resources and network connection speeds. We propose a task partitioning and scheduling mechanism which results in distribution of N tasks with various real-time constraints and work loads on M heterogeneous devices.It has been shown that in case of M=1 an optimal solution to task scheduling can be obtained with computational complexity O(N) however for M≥2 the scheduling algorithm can be demonstrated to be NP-hard by reducing it to the well known NP-Complete bin-packing problem The mechanism proposed in this paper considers device capabilities, Link capacities and task constraints to find a near optimal solution to the multimedia scheduling problem in Ad hoc networks.
