An Efficient Path Computation Model for Hierarchically Structured Topographical Road Maps
In this paper, we have developed a HiTi (Hierarchical MulTi) graph model for structuring large topographical road maps to the minimum cost route computation. The HiTi graph model p...

Value-aware Resource Allocation for Service Guarantees in Networks
—The traditional formulation of the total value of information transfer is a multi-commodity flow problem. Here, each data source is seen as generating a commodity along a fixe...

Performance analysis of opportunistic broadcast for delay-tolerant wireless sensor networks
This paper investigates a class of mobile wireless sensor networks that are unconnected most of the times; we refer to them as delay–tolerant wireless sensor networks (DTWSN). T...

Approximation Ratios of Multicast Light-Trees in WDM Networks
Abstract--All-optical multicast routing (AOMR) is implemented by the concept of light-tree in WDM networks. The costoptimal multicast light-tree is NP-hard to compute, especially w...
