Routing on spatiotemporal networks without global knowledge
نویسنده
چکیده
The formulation of most shortest-path problems makes two simplifying assumptions: (1) the edge weights are deterministic, and (2) global knowledge of the network is available. I develop a decentralised routing algorithm providing en-route guidance for travellers without global knowledge on spatial networks with stochastic edge weights. The algorithm guides travellers using an estimation function that gauges cumulative arrival probability distributions based on the distance between nodes. The estimation function carries a notion of proximity between nodes and enables routing without global knowledge. I develop a new criterion to discriminate among these distributions and compare decentralised algorithms with centralised ones.

Improvement of Routing Operation Based on Learning with Using Smart Local and Global Agents and with the Help of the Ant Colony Algorithm
Routing in computer networks has played a special role in recent years. The cause of this is the role of routing in a performance of the networks. The quality of service and security is one of the most important challenges in routing due to lack of reliable methods. Routers use routing algorithms to find the best route to a particular destination. When talking about the best path, we consider p...

متن کاملBroadcast Routing in Wireless Ad-Hoc Networks: A Particle Swarm optimization Approach
While routing in multi-hop packet radio networks (static Ad-hoc wireless networks), it is crucial to minimize power consumption since nodes are powered by batteries of limited capacity and it is expensive to recharge the device. This paper studies the problem of broadcast routing in radio networks. Given a network with an identified source node, any broadcast routing is considered as a directed...
متن کاملDecentralized Routing on Spatial Networks with Stochastic Edge Weights
We investigate algorithms to find short paths in spatial networks with stochastic edge weights. Our formulation of the problem of finding short paths differs from traditional formulations because we specifically do not make two of the usual simplifying assumptions: (1) we allow edge weights to be stochastic rather than deterministic and (2) we do not assume that global knowledge of a network is...
متن کاملNavigability of Complex Networks
Routing information through networks is a universal phenomenon in both natural and manmade complex systems. When each node has full knowledge of the global network connectivity, finding short communication paths is merely a matter of distributed computation. However, in many real networks nodes communicate efficiently even without such global intelligence. Here we show that the peculiar structu...
