This paper proposes a new approach for infrared object localization and tracking with passive infrared sensors (PIR). The hierarchical architecture visibility of Fresnel lens away is presented with modulated field of view (FOV). The FOVs of lens array in sensor node are modulated to achieve a single degree of freedom (DOF). The energy imbalance problem effectively solve with the PIR system. PIR based system saves power consumption and memory space. Passive infrared system detects the change in the radiation of warm blood generation and completely used to turn On the webcam and lighting system.

Vehicular Ad-hoc Network is an infrastructure less network, which helps in creation of network due to road side units and vehicles as the communicating nodes. The wireless connections help in communication process among the nodes. It leads to a reduction in traffic congestion and vehicles crashes. Recently many research authorities and automotive industries have started exploring this area as new field of research and development. The challenges associated with this field are studied. In this paper, the factor being chosen is the routing protocols in these networks which are used for routing of data .The throughput and average end to end delay performance metrics are used for comparison of reactive and pro-active routing protocols.
