The most commonly pirated mobile apps are games and utility apps.

Therefore, VANET’s plays major role in development of ITS. Such applications require highly reliable communication paths and stable cooperative nodes to support high quality data delivery within expected time. Earlier, a lot of research has been carried out in this area using network formed by vehicles alone and efficiently handles path construction process. But, in certain situations like when the cluster head not able to find an immediate neighbor for forwarding critical information through network might causes inconvenience, also chances of great damage for vehicles along the path. To address this issue in our proposed model, both vehicles and mobile nodes is used dynamically to establish a path depending on situation.

Prevention-based and detection based are the two approaches that are used in MANET. In prevention-based approaches a centralized key management is required, These applications require a good Quality of Service (QoS) from sensor networks, such as, minimum percentage of sensor coverage in the required area, continuous service during required time slot with minimum (or limited) resources (like sensor energy and channel bandwidth) and minimum outside intervention. The whole network may be affected if the infrastructure is destroyed. So this approach is used to prevent misbehavior, but not detect malicious based routes Detection based approaches are used to detect selfish node along with route that helps to identify malicious misbehavior route. Detection based approaches are based on trust in MANETs. Hence this approach is used to calculate the trust value in trust management schemes. The proposed scheme differentiates, routes, data packets and control packets, and also excludes the other causes that results in dropping packets, such as unreliable wireless connections and buffer overflows.

An antenna is a transducer that converts electrical signals into EM waves and radiates into space. The performance of an antenna is measured by its parameters namely bandwidth, gain, return loss etc. There are several types of antennas available but the microstrip patch antennas are widely used for many applications because of its low profile, light weight, low cost, feed-line flexibility, versatility, ease of fabrication etc. Even though it has several advantages, it suffers from major drawbacks namely narrow bandwidth, low gain and high return loss. In order to overcome these drawbacks, FR-4 materials are used. Specific absorption rate (SAR) is a measurement of certain amount of radiation absorbed by human body while entering into an electromagnetic field. It is defined as the power absorbed per mass of tissue and has units of a watt per kilogram. SAR is typically averaged either over the complete body or over a small sample volume (typically 1g or 10g of tissue). For evaluating the antenna performance, gain, VSWR and the return loss were calculated for the proposed antenna and the proposed antenna provides the peak the gain of 4.43dB at 10.846GHz. The proposed antenna also provides the SAR value of 0.00109W/Kg is evaluated for 1g of tissue as per the IEEE standard.
