Active group route guidance based on DODE: A novel modeling framework integrating dynamic driver behavior

This work aims to provide effective and reliable traffic guidance strategies for improving the system performance and travel reliability, wherein the drivers’ route diversion behavior is the key determinant in these strategies. This study presents a novel modeling framework that can incorporate the dynamic driver behavior into a real-time group route guidance model based on dynamic origin–destination demand estimation and prediction (DODE) for information-based active traffic management. Experiments are conducted to test the effectiveness of the proposed model on the basis of the traffic dataset of the Route Guidance Pilot Project. Experimental results show that the effect of route diversion on DODE under information provision, which can improve the accuracy of DODE, must be considered. Compared with the traditional guidance model, the proposed model considers the system objective and the actual route diversion behavior and can provide better performance and ensure system sustainability.

SRDP: Secure Route Diversion Policy for Resisting Illegitimate Request in MANET

Optimized Link Source Routing (OLSR) is currently identified as one of the robust on-demand protocol in Mobile Adhoc Network (MANET) for offering good communication performance. However, there are very less evidence where it is found to support potential security. After reviewing existing security approaches in MANET, it is found that there is a still an open scope of security in MANET where the potential of OLSR can be harnessed. Hence, this manuscript presents SRDP or Secure Route Diversion Policy that is capable of identifying the incoming threat irrespective of any form of attacks. SRDP allows comprehensive identification of threat and it offers safety to the network by further resisting such incoming messages to be propagated within its secured network. The study outcome shows that SRDP offers good communication performance and retain good balance with cost effectiveness in contrast to existing security schemes.

DESIGNING A MAINTENANCE FREE MULTI-CHANNEL WIRELESS SENSOR NETWORK PROTOCOL

Wireless sensors are low powered device that is scattered to monitor its surroundings. These energy-constrained devices are usually constructed in a hierarchical structured manner where after sometime some of the nodes may deplete energy resulting disruption of the routing topology in a wireless sensor network. A faulty parent node may cause the reconstruction of the network’s routing topology if a maintenance solution is not provided to the protocol. Thus this study focuses on the maintenance free environment for a multi-channel wireless sensor network. A tree-based solution is proposed for the multi-channel protocol and a route diversion is proposed for the maintenance solution. The multi-channel characteristics is used as a tool to determine the route diversion of the children node. A simulation is built to compare the proposed protocol with existing tree-based multi-channel protocol. The result of the proposed protocol shows an improvement to the packet delivery rate by 15%.
