Dynamic probabilistic routing discovery and broadcast schemes for high mobility ad-hoc networks

  Mobile ad-hoc networking (MANET) technology has been a major avenue for many wireless and mobile networked based applications in different fields including, but not limited to, industry, military, and public services including the emerging ones such as the intelligent transport systems (ITS) that aim to enhance the road safety [1]. In ITS, MANETs are used to disseminating a warning messages between cars on the roads about road accidents, emerging regulations or weather related information. In addition MANETs can be used effectively in rescue management operations in urban and rural areas [2]. The self configuration, self healing, the non-infrastructure nature, high mobility, ease of implementation and cost-effective operation are among the major desirable characteristics of this networking technology.
Indeed, the broadcast communication (or one-to-all communication) is one of the most primitive collective capabilities of any network. It is also central to many important group based applications, and fundamental to the implementation of other group communication based operations. Furthermore, broadcast is widely used to send information messages between nodes in many applications such as real-time applications including online TV, distance learning and gaming and so forth. Nevertheless, existing broadcast schemes in MANETs suffer in terms of several issues such as rebroadcast redundancy and collisions. Consequently, this degrades the communication quality especially when dealing with high bandwidth applications. Thus, this study adopts a new strategy to handle the broadcast operation efficiently by reducing the number of the broadcast redundancy request (RREQ) packets and the number of collision and contentions.
