In this paper, the cluster-based network architecture combined with multi-hop transformation is studied and a hop-number-constrained multi-hop routing algorithm (HMR) is proposed. This new scheme is designed to prolong the network lifetime. In order to make sure that the communication period from sensor nodes to base station is stable, in this new scheme, the maximum hop-number is considered. Meanwhile, nodes with higher residual energy undertake more tasks of relaying information so as to balance the energy consumption in the network. Simulation results show that this new scheme provides longer lifetime than the classical clustering algorithms, and HMR also reaches larger amount of effective messages.

In wireless sensor networks (WSNs), energy consumption is crucial. routing plays a very high role for energy optimization, as taking less hop numbers usually leads to a better performance. The main goal of this paper is to provide an energy saving routing algorithm that is simple to understand and implement, and that is inspired by the work in the field of swarm intelligence. Basing on the idea that transmission consumes more energy than processing, the routing algorithm avoids this by only sending updates to neighbors when a critical event occurs (e. g. the node's energy dropping to zero), with the objective that this type of events do not impact negatively in the network. The selection of a path is based on the neighbor with fewer hops and less pheromone concentration, to avoid overusing of a route, all this being calculated by each node's own processing.

As a nanometer level network-on-chip with the optical interconnection, the Optical Network-on-Chip (ONoC) was first proposed in 2006 in order to reduce the power consumption of the inter-chip communication. Because ONoC is typically characterized by low latency, high bandwidth and low power consumption, it has become more and more attractive. Compared with the 2-Dimensional (2D) design, the 3D integration technology has a higher packing density, a shorter wire length and the less power consumption. Therefore, the 3D ONoC will have the great potential in the future. In this paper, we first discuss and study the ONoC, and we then design the 3D mesh ONoC from the perspectives of topology, routing and communication protocol, with the help of 3D integration advantages. We setup a simulation platform by using OPNET in order to compare the performances of 2D and 3D mesh ONoCs in terms of the average delay and the data packet loss rate. The simulation results demonstrate that our 3D mesh ONoC is actually effective.

Double loop networks are an important class of networks. Their structureis symmetric, simple, and expandable. Therefore they can be used extensively inthe topology design of computer networks. The graphic theory model of doubleloop networks is a circulant digraph G(N;r, s). The routing of C(N;r, s) has beenintensively investigated by researchers both in computer science and graph *** a number of results have been published for the case of r = 1. This paperinvestigates the structure characteristic of circulant digraph when r and s are arbitrarypositive integers. The paper partitions the vertex set off several disjoined subsets andprovides an optimal routing algorithm for circulant digraph which bases upon thevertices set partition. This paper also considers the vertex fault-tolerant, gives aformula for the vertex fault-tolerant diameter and presents an optimal vertex fault-tolerant algorithm.
