An Energy-Aware Routing Protocol Based on Effective Transmission in Sensor Networks

In order to minimize the energy consumption in the discovery of the routing path, this paper introduces a novel concept of effective transmission （ET） that ensures each forwarding node is not only farther from the source node, but also nearer to the destination node with respect to its sender, An energ-aware routing protocol based on ET is proposed. It enables the energy consumption for each hop to be the least for the transmission. The simulation results show the routing protocol is effective in the performance of energy consumption comparing with some other routing protocols.     

A Partially Non-Cryptographic Security Routing Protocol in Mobile Ad Hoc Networks

In this paper, we propose a partially non-cryptographic security routing protocol （PNCSR） that protects both routing and data forwarding operations through the same reactive approach. PNCSR only apply public-key cryptographic system in managing token, but it doesn＇t utilize any cryptographic primitives on the routing messages. In PNCSR, each node is fair. Local neighboring nodes collaboratively monitor each other and sustain each other. It also uses a novel credit strategy which additively increases the token lifetime each time a node renews its token. We also analyze the storage, computation, and communication overhead of PNCSR, and provide a simple yet meaningful overhead comparison. Finally, the simulation results show the effectiveness of PNCSR in various situations.

A Layered Zone Routing Algorithm in Ad Hoc Network Based on Matrix of Adjacency Connection

The hybrid routing protocol has received more attention recently than the proactive and the reactive, especially for large-scale and highly dynamic connection, in mobile ad hoc network. A crucial reason is that zone-layered is being utilized in the complex systems. A hybrid routing algorithm which is layered zone based on adjacency connection（LZBAC） is put forward under the background of a few members in network with steady position and link. The algorithm modifies storage structure of nodes and improves routing mechanism. The theoretical analysis and simulation testing testify that the algorithm costs shorter time of route finding and less delay than others.     

移动Ad Hoc网中基于QoS的功率优化自适应多业路由协议

移动Ad Hoc网是一种由移动节点组成、拓扑结构动态变化的自组织网络。在网络中没有固定的基础设施，移动节点既是通信主体，又承担报文转发的功能。由于其与众不同的特点，路由的选择就变得特别重要。在已存的路由协议中，主要考虑提供单业务路由，而对多业务路由则较少涉及。提出了一种充分考虑功率优化和QoS要求的多业务路由协议，通过发射较大的功率来建立最大功率的满足QoS要求的路由，同时通过中间节点的窃听和重定向来建立功率优化的路由，然后根据不同业务来选择不同的路由进行通信。通过比较发现，此协议能够提高网络的综合性能。
