Optimized Link State Routing

Video services are much demanded nowadays but bandwidth and delay requirements of this kind of services are very restrictive. Offering real-time video services in wireless ad-hoc networks is not an easy task because of the difficulty of guaranteeing certain quality in a shared medium. Practical solutions should try to improve communications at (and gathering information from) several layers of the protocol stack. Mobile Ad-hoc Networks are infrastructure-less wireless networks characterized by being very versatile, dynamic and self-organized but also by the difficulty to achieve a good Quality of Service in video transmissions due to packet losses and node mobility. On the other hand, the Wireless Mesh Network is presented as the next step in wireless networks. Wireless Mesh Networks have a hierarchical topology, clustered structure and static backbone, which all help to improve the network stability. In the way towards Wireless Mesh Networks, hierarchical routing protocols could transform an ad-hoc network in a more robust wireless network. Therefore, in this chapter, hierarchical routing protocols have been studied, particularly Hierarchical Optimized Link State Routing Protocol, and compared with a traditional flat routing protocol named Optimized Link State Routing. Furthermore, additional video coding techniques have been used in order to improve video quality in reception. At application layer, results show that Multi-description Coding achieves better quality on video transmissions when nodes have medium or high mobility, especially when using multipoint-to-point transmission or disjoint paths in a hierarchical structure. Video trace simulations have allowed us to perform subjective quality tests to assert the Quality of Experience improvements in video transmissions.

Ad hoc networks enable network creation on the fly without support of any predefined infrastructure. The spontaneous erection of networks in anytime and anywhere fashion enables development of various novel applications based on ad hoc networks. However, ad hoc networks present several new challenges. Different research proposals have came forward to resolve these challenges. This chapter provides a survey of current issues, solutions, and research trends in wireless ad hoc networks. Even though various surveys are already available on the topic, rapid developments in recent years call for an updated account. The chapter has been organized as follows. In the first part of the chapter, various ad hoc network issues arising at different layers of TCP/IP protocol stack are presented. An overview of research proposals to address each of these issues is also provided. The second part of the chapter investigates various emerging models of ad hoc networks, discusses their distinctive properties, and highlights various research issues arising due to these properties. The authors specifically provide discussion on ad hoc grids, ad hoc clouds, wireless mesh networks, and cognitive radio ad hoc networks. The chapter ends with a presenting summary of the current research on ad hoc networks, ignored research areas and directions for further research.

Self-Organized Networks (SONs) are an advancement of today's communication that arises to overcome the problems in traditional communications in terms of their planning, configuration, optimization, healing and management since the rate of utilizing communication technology is gradually increasing day by day hence an optimum mechanism is needed to cope up with all the changes in the communication era, the result is self-organized networks. The success of SONs depends on how it is effectively utilized without any compromise in its security. However its unique characteristics offer both opportunities and challenges. The aim of this chapter is to begins with the essential concept of SONs such as Mobile Ad Hoc Networks (MANET), Vehicular Ad Hoc Networks (VANET), Wireless Sensor Networks (WSN), Wireless Mesh Networks (WMN), Peer to Peer Networks (P2P), Cognitive Radio Networks, Bio-Inspired Networks and Internet of Things (IoT) and their limitations in different perspectives. As these networks have penetrated into the human life with an anytime anywhere capability, the security of the data being processed and communicated through these networks become vital. This chapter tries to bring out the issues and challenges in providing a trust based solution mechanisms for this type of networks.

Now a day, every one using mobile devices for communicating with others. The development of new technologies, like Internet of Things (IoT) needs coverage, connectivity, scalability and QoS. In ubiquity networks, the major issues are coverage, connectivity, scalability and QoS. To solve these limitations, integrating wireless networks with ad hoc networks. This paper provides detail survey on how ad hoc networks are integrated with Cellular Network, Wireless Mesh Networks and Wireless Sensor Networks. This integration may resolve the problems of coverage, connectivity, scalability and QoS.
