Interest in the research and development of MANETs has experienced a dramatic growth owing to the advancement of new technologies such as GPS, Bluetooth, WLAN, Wi-Fi, DVB-H, RFID & UWB. A Mobile ad-hoc network is an accumulation of wireless nodes forming a provisional network without any pre-established communication infrastructure. To facilitate communication within such networks, a routing protocol is used to discover and establish routes between a pair of nodes, so that message can be delivered in a timely manner. However, mobility patterns have significant effect on the performance of routing protocols and hence on MANETs. The same routing protocol can perform differently in different mobility model. This book, therefore, attempts to provide a comprehensive study and analysis of proactive and reactive routing protocols behavior over realistic environment model under QoS constraints. It also provides detail simulation setup and results and investigation of mobility models impact on mobile ad hoc networks for varying number of traffic sources, number of nodes, speed, and data transmission rates. Finally the book concludes by recommending a set of problems for further research.

With the advancement of wireless technology, vehicular ad hoc networks (VANETs) are emerging as a promising approach to realizing "smart cities" and addressing many important transportation problems such as road safety, efficiency, and convenience.§This brief provides an introduction to the large trace data set collected from thousands of taxis and buses in Shanghai, the largest metropolis in China. It also presents the challenges, design issues, performance modeling and evaluation of a wide spectrum of VANET research topics, ranging from realistic vehicular mobility models and opportunistic routing, to real-time vehicle tracking and urban sensing applications. In addition to the latest research and techniques, the reader will also learn the trace-driven methodologies and tools of performance modeling and analysis, network protocol design and optimization, and network simulation, thus keeping pace with the fast moving VANET research and development.

Ad hoc networks have a great importance in modern§scientific and technological usage. Ad hoc network§does not need a topology,infrastructure and special§management. Security limits its functionality§specially in unsecured environment. This work comes§to solve this problem by modifying one of the used§protocols in ad hoc networks, which is Ad Hoc§On-demand Distance Victor(AODV) routing protocol that§depends on finding route path just when need to. This§modification has done by using some reserved bits§from Route Request(RREQ) packet to add security§feature by selecting encryption algorithm to protect§payload data that is transferred between nodes of§communication by considering workload level at each§node when selecting route path. In addition, this§work presents a technique for distributing public key§to be used within RSA algorithm by adding a new part§to RREQ packet. The performance of the standard and§modified AODV protocol also studied in this work by§considering some parameters that affect ad hoc§network performance, which are mobility and number of§nodes while communication process.

Research Paper from the year 2007 in the subject Computer Science - Internet, New Technologies, printed single-sided, grade: PG, VIT University (Net Research Labs), 26 entries in the bibliography, language: English, abstract: One of the major challenges faced by MANET researchers is the deployment of end-to-end quality-of-service support mechanisms for streaming media services over a group of MANET users. Group-oriented services over large, dynamically changing MANET networks has a big impact on the needs of streaming services communication in terms of mobility, quality of service (QoS) support and multicasting. In MANET networks, where such features are not embedded with its architecture, it is necessary to develop QoS multicasting strategies. The research work focuses on the basic building blocks of an mobile ad hoc group communication scheme, which achieves multicasting optimal QoS efficiency OptiQ by tracking resource availability in a node s neighborhood based on resource reservations, which announces the required QoS before each session initiation. The primary quality of service (QoS) issues such as required bandwidth, message delay, traffic type and hop count per route improves the efficiency of streaming services over ad-hoc network. Streaming services support voice, data and video traffic by assessing and adjusting for various levels of QoS. The performance analysis is performed on functional prototype of OptiQ in mobile / wireless ad-hoc network with emphasis on service satisfaction for multiple group conference sessions. The performance of OptiQ scheme is well compared with QoS-aware versions of AODV and TORA, well-known ad-hoc routing and limited QoS protocols. Using the SPRUCE bandwidth traffic gathering tool, with a set of C++ modules an extensive set of performance experiments were conducted for these protocols with OptiQ on a wide variety of mobility patterns and reservation strategies. The results shows the performance analysis of OptiQ is better than AODV or TORA protocol in minimizing end-to-end delay and controlling loss.
