India is the second largest country in the category of population. With the increasing population the consumption of the vehicles also increases, leading to critical burden on traffic management in the metropolitan cities and towns of the country. In 2011-12 alone, 20.4 million motorized vehicles were sold in India leading to congestion and accidents on the roads. For controlling the traffic on the road some traditional methods were used like using traffic lights and traffic signs, traffic policemen and roundabout. In this paper we will discuss the existing techniques which will help India for controlling the traffic on the roads.

Abstract. To become independent of backbone networks leading to cheap deployments, the traditional single-hop approach needs to be replaced by Wireless Mesh Networks (WMNs). Wireless Mesh Networks is cost-effective alternative to wireless local area networks. Due to multi hop networking, WMN requires multi hop routing protocol. Mostly the nature of data is from client to gateway and vice versa. So, according to IEEE 802.11s Draft 3.0, HWMP routing protocol is adopted. In this paper, we analyzed the throughput of HWMP protocol with increase in number of nodes and increase in size of packets using simulation model.

In recent years, mesh networking has emerged as a key technology for the last mile Internet access and found to be an important area of research and deployment. The current draft standard of IEEE 802.11s has defined routing for Wireless Mesh Networks (WMNs) in layer-2 and is termed as Hybrid Wireless Mesh Protocol (HWMP). However, security in routing or forwarding functionality is not specified in the standard. As a consequence, HWMP in its current from is vulnerable to various types of routing attacks such as flooding, route disruption and diversion, spoofing etc. In this paper, we propose a secure HWMP routing protocol for WMN. The proposed protocol uses cryptographic extensions to provide authenticity and integrity of HWMP routing messages and prevents unauthorized manipulation of mutable fields in the routing information elements. We will show that the proposed protocol successfully thwarts all the identified attacks.
