The maximum benefit out of the recent developments in sensor networking can be achieved via the integration of sensors with Internet. The real-time specific sensor data must be processed and the action must be taken instantaneously. The integration controller module of the proposed architecture integrates the sensor network and Internet using Cloud Technology which offers the benefit of reliability, availability and extensability.

Wireless ad hoc networks are an emerging multi-hop communication system among mobiles to deliver data packets. The special characteristics of wireless networks make the communication link between mobiles unreliable. To handle high mobility and environmental obstacles, most physical routing protocols do not consider stable links during packet transmission, which leads to higher delay and packet dropping in network. In this paper, we propose path observation-based physical routing protocol named POPR for WANET. The proposed routing protocol incorporates relative distance, direction and mid-range forwarder node with traffic density to forward the data towards destination in order to improve physical forwarding between and at the intersection. Simulation results show that the proposed routing protocol performs better than existing solutions.

Cloud Computing aims to provide computing everywhere. It delivers computing resources on demand over internet in terms of anything anywhere anytime concept. It provides everything as a service to its users like infrastructure platform software hardware workplace data and security. Cloud computing has made revolutionary transformations in the government and business. Cloud Computing transforms the databases and application software to the huge data centers, where the management of the services and data may not be trustworthy. To verify the correctness, integrity, confidentially and availability of data in the cloud, in this paper, we focus on various cloud computing security threats and solution that have been used since security is an important measure for quality of service.
