In Vehicular Ad-hoc Network (VANET), the multi-hop routing frequently breaks off, which has a negative effect on the reliability and transmission quality of the network. The paper proposes a new routing algorithm based on the geographical position, called Multi-Priority Opportunistic Directional Routing (MPODR). The algorithm improves the existing Opportunistic Directional Forwarding Strategy from...
In current research self-security management is of high interest. Wireless Ad hoc networks use mobile nodes to enable communication outside wireless communication zone. Attacks on wireless ad hoc network routing protocols disrupt network performance and reliability. In active black hole attacks on wireless networks; malicious nodes advertise the shortest path through the, between source and destination,...
This study evaluated the level of performance improvement in the form of a simulated experiment by adding fixed node in the middle of the network as a way to improve mobile ad.hoc network performance. The result showed that the performance level was much higher when fixed node was used together than when mobile node was used only, and the comparison of the mobile speed of mobile node also showed that...
Wireless Mesh Networks (WMNs) are dynamically self-organized and self-configured, with the nodes in the network automatically establishing an ad hoc network and preserving the mesh connectivity. There are several features which might help to design an efficient routing protocol suitable for wireless mesh networks such as improved performance metrics, link or path optimization, mobility management,...
The stability and reliability of routing protocols in existence can not be well adapted to mobile ad hoc network, which is always shorted for MANET. In this paper, a novel routing algorithm is proposed and evaluated to reduce the overhead as well as to enhance the network stability for MANET. The thought of design came into being based on the way of ants foraging and work dividing. By making a selective...
The significant goal of routing protocol designs for wireless sensor networks is to improve the utilization rate of nodes and to prolong the lifetime of the network. But to a specific application, some other network performances, such as robustness, reliability, end-to-end delay, should be concerned and the conventional single path schemes may not be optimal to improve all these performances efficiently...
The probability of successful packet delivery in ad hoc networks can be guaranteed by multi-path routing scheme, which can enhance network reliability. With the analysis on the path number, a decision making method based on packet drop ratio is introduced; moreover, a novel adaptive multi-path routing protocol is proposed. By monitoring packet drop ratio on the links, mobile nodes estimate link status...
Mobile ad hoc network (MANET) is a self-configuring network that is formed automatically via wireless links by a collection of mobile nodes without the help of a fixed infrastructure or centralized management. The mobile nodes forward packets for each other, allowing communication among nodes outside wireless transmission range hop by hop. Due to dynamic infrastructure-less nature and lack of centralized...
