Seamless Connectivity in Vehicular Networks, and Vehicle Security is attracting discussion of research issues related to the integration and cooperation of heterogeneous wireless networks, (i.e. IEEE 802.11p, IEEE 802.16e, and dedicated short-range communications (DSRC) as well as seamless connectivity in vehicular scenarios. Research into vehicle security control technology also suggests that more improved monitoring and security offering embedded communication is required. As a result a viable security system needs to be in constant communication with a base station for monitoring purposes. Direct Sequence Spread Spectrum (DSSS) technology offers a secure solution due to excellent interference suppression of non-Gaussian noise and interference. This paper offers an architecture that will utilize a hybrid smart grid technology, wireless and powerline communication (PLC) as a medium. This paper suggests that using microprocessor technology to generate short message bursts utilising hybrid transmission mediums will allow for efficient and accurate transmission with low Bit Error Rates (BER). Remote immobilizer functionality is the ultimate aim of this research. The aim is to offer after-theft security a function that can be used as a Stolen Vehicle Tracking (SVT) system through Hybrid communication through current available protocols.
