We have proposed an algorithm for optimal real-time routing in multi-hop communication networks for multi-source/multi-sink connection. The algorithm deals with various capacity constraints in terms of communication limits and real-time constraints expressed as deadline for each particular flow of data. The objective is to find the optimal routing in terms(More)
This work proposes a distributed algorithm for the energy optimal routing in wireless sensor network. The routing problem is described as a minimum-cost multi-commodity network flow problem by Linear programming. Based on the convex programming theory we use the dual decomposition theorem to derive the distributed algorithm. The algorithm computes the(More)
This work proposes a novel in-network distributed algorithm for real-time energy optimal routing in ad hoc and sensor networks for systems with linear cost functions and constant communication delays. The routing problem is described as a minimum-cost multicommodity network flow problem by linear programming and modified by network replication to a(More)
