TL;DR: RAS: a Reliable routing protocol for enhanced reliability and security of communication in mobile Ad hoc and Sensor networks and results show an improvement in the reliability of the discovered path with the proper choice of certain important reliability parameters.
Abstract: Routing protocols in mobile ad hoc and sensor networks discover a multi-hop route between source and destination nodes. A highly reliable path is an important component for enhancing the security of communication. This paper presents RAS: a Reliable routing protocol for enhanced reliability and security of communication in mobile Ad hoc and Sensor networks. Enhanced reliability and security are achieved by the maintenance of a reliability factor by the nodes, which is increased when nodes participate successfully in data transmissions. This is determined through the use of positive and passive acknowledgements. Additional optimizations are included in order to increase the efficiency and performance of the network. Simulation experiments are performed in order to verify the operation of the proposed protocol and evaluate its performance. The results show an improvement in the reliability of the discovered path with the proper choice of certain important reliability parameters.

TL;DR: This work proposes a V2V streaming on OMNet platform (VSOP) to build a V1V evaluation of real-time multimedia streaming under TCP/ UDP on VANET, and analyzes and simulates the routing performance in VANet.
Abstract: Ad hoc network is composed of mobile nodes without infrastructure. Depending on a hop-by-hop basis of connection, communications between high-mobility nodes are accomplished via cooperative forwarding. Especially, the vehicular ad hoc network (VANET) is a technology that uses moving cars as nodes to create a mobile network or implement vehicle-to-vehicle (V2V) connection. However, the discussion about live streaming or comparative performance in V2V has been lacked so far. We propose a V2V streaming on OMNet platform (VSOP) to build a V2V evaluation of real-time multimedia streaming under TCP/ UDP on VANET. We not only compare TCP and UDP, but also analyze and simulate the routing performance in VANET. The major contribution of proposed scheme is a compared study of protocols for real-time wireless application.

TL;DR: This study defines a generic and simple model for links and paths stability in MANETs and investigates the effect of mobility under various scenarios, showing that the model is perfectly capable of predicting the behavior of links and path and that proactive routing always constructs low stability paths even under slow moving nodes.
Abstract: A mobile ad hoc network (MANET) is a collection of autonomous mobiles nodes forming a temporary network without using any existing infrastructure or centralized administration. MANETs are characterized by a dynamic topology which makes routing a critical task. Conventional routing protocols are mainly based on shortest paths computation which could be not effective facing the mobility of nodes. Therefore, finding stable paths in MANETS is a more reliable strategy to improve routing. In this paper, we study the stability of links and paths in MANETs. At that end, we define a generic and simple model for links and paths stability in MANETs, then, we investigate, using the new defined metrics, the effect of mobility under various scenarios. Our study showed that our model is perfectly capable of predicting the behavior of links and paths and that proactive routing always constructs low stability paths even under slow moving nodes.

TL;DR: The statistic results of link and path availability properties in MANET were derived, and a pseudo gossip routing algorithm based on the link stability was proposed, which can select a reli-able path that can last longer by using fewer routing messages.

TL;DR: It is found that OLSR can create links when buildings are not considered, but when buildings is considered some islands are created in the network and there are a lot of disconnections.
Abstract: In recent years, Vehicular Ad-hoc Networks (VANETs) have emerged as a unique type of MANETs. VANETs are an important component of the Intelligent Transportation Systems (ITS). They can be utilized to guarantee road safety, avoid potential accidents and create new forms of inter-vehicle communications. In this paper, we investigate the performance of OLSR protocol for video streaming application. The simulations are conducted in urban environment in two scenarios with and without buildings. We consider 802.11p standard and send multiple video streaming flows over UDP. We use throughput, delay and jitter as evaluation metrics. Based on simulation results, we found that OLSR can create links when buildings are not considered, but when buildings are considered some islands are created in the network and there are a lot of disconnections.
