A distributed algorithm is proposed which routes packets to minimise the expected latency in arbitrarily connected mesh networks, where each link has a set transmission rate. It is proven that the proposed algorithm converges to the global minimum. Initial simulations demonstrate the effectiveness of the proposed algorithm relative to current methods based on Dijkstra's algorithm.
Space based Internets will be used to move earth observation data through satellite constellations to ground based receiving stations. Routing observation traffic in this environment is constrained by individual satellite orbits, individual satellite capabilities, observation schedules, ground station schedules, and rapidly evolving natural events. Among many global routing algorithms, Dijkstra algorithm...
This paper presents a proposal of a Routing and Wavelength Assignment algorithm that use a routing strategy taking into account monitored physical layer attributes as input parameters for the path computation. The proposed routing technique aims at to achieve optical quality of service (OQoS) in optical network impaired by Polarization Mode Dispersion (PMD). Numerical results show that the network...
In this paper we present a MANET proactive routing enhancement scheme by comprehensive evaluation of multiple dynamic routing metrics, including delay, energy cost, and link stability. We developed efficient routing metric prediction methods: predicting delay and energy using double exponential smoothing, and predicting link stability using a heuristic based on the normal-like distributions of the...
In wireless sensor network, a lot of sensory traffic with redundancy is produced due to massive node density and their diverse placement. This causes the decline of scarce network resources such as bandwidth and energy, thus decreasing the lifetime of sensor network. Recently, mobile agent is proposed as a solution to overcome these problems. Mobile agent accounts for performing data processing and...
In communication networks where (1) some nodes are capable of correcting up to a maximum number of erasure, and (2) the nodes are connected by the q-ary symmetric erasure channels parametrized by their bit erasure ratios (BER); it is often possible to find the path with minimum (zero) worst possible erasure. We introduce (1) the BER and worst-case erasure (WCE) metrics and (2) an algebra equipped...
