Due to the increase in popularity of wireless networks, there is a need of combining various heterogeneous networks to provide global information access to the user. Vertical handoff is an exciting and a latest scheme that intends at combining different network interfaces. The most decisive parameter which plays an important role in certain mobile nodes is battery power. Due to the complexity of vertical handoff algorithms previously developed, the battery power of certain mobile nodes is almost exhausted at the end of execution of algorithm. Moreover, as mobile nodes operate with limited battery power, when battery level falls below a specific level, handing off to a network with low power consumption can provide extended usage time. Thus there is a necessity to develop a vertical handoff algorithm with minimum complexity. In this paper, a new vertical handoff algorithm is developed which aims at taking an optimal handoff decision using two simple steps. Unlike the previous developed algorithms, this algorithm discriminates resource rich and resource poor mobile stations during the execution of the algorithm. Due to the consideration of dynamic new call blocking probability during handoff decision, this algorithm helps in connecting to the optimal network in the vicinity of the mobile station.Keywords

Avoiding collision of the Autonomous underwater vehicle (AUV) with the floating or fixed objects in the underwater scenario needs either apriori knowledge of the operating environment or sensing equipment for evaluating the environment in real time. The sensing equipment in this case is the forward looking Sonar that is mounted on the AUV which scans the area in front and provides the images as the output. The technology used in this forward looking SONAR is CHIRP. In SONAR, Surface Acoustic Wave devices such as Reflective array Compressors are used to generate the chirped signals. Because of Chirp technology high resolution images of sea bed are produced. The range resolution of the CHIRP technology SONAR is much better than conventional monotonic SONAR. With monotonic SONAR it is very difficult to differentiate two objects separated by less than 37.5 mm whereas using CHIRP technology SONAR it is easy to distinguish the objects if they 7.5mm apart. In this paper the generation of Chirp pulse is analyzed. The pulse compression technique and different windowing techniques are analyzed to detect the peak of the received signal.

Among all agricultural farm inputs like seed, soil, machinery, fertilizer, irrigation etc. A good quality seed is a considered as major important farm input as it directly contributes to a good crop production which further makes farmer to earn income by marketing the surplus to consumers. Different seed brands are realised by public and private companies in the market which is becoming a challenging for farmer to choose a good quality seed brand for cultivation purpose. As tomato is considered as one of most profitable crop, majority of the farmers choose it for commercial purpose. A study was made to know about the farmers’ brand preference towards tomato seed and finding the reasons that making farmer to choose a specific brand. Study has conducted by choosing two blocks i.e., Mulakalacheruvu and Nimmanapalle of Chittoor district and information was collected from 120 sample farmers from cluster of villages through random sampling procedure. Top eight brands of tomato seed were taken for study and ranking was done through simple weighted average method and it was found that majority of the farmers prefer SAHOO (TO-3251) followed by PHS SWEAKAR (448). Because of its characteristics of high yield and resistance to pest and diseases and when specific brand gives good crop yields for farmers, then the studies analysed that there will be repetitive purchase of that brand and farmers will shift irrespective of considering the cost of seed.Keywords
