It will integrate the current co-existing wireless networks to allow the users to connect to the network that best suits their needs. The next generation wireless networks are characterized by anywhere, anytime connectivity, enhanced data services and higher data rates to end-users. This infrastructure will also support efficient handovers. Heterogeneous networks aim to achieve this. To facilitate new services, and make them flexible and bandwidth efficient, vertical roaming of mobile nodes is a tempting possibility for operators. Our project deals with reduction of power consumption during handovers. If the user call is based on previous history, the handover takes place without calculations and we have achieved a power saving of 28.38%. Also our proposed algorithm tries to select an appropriate target network for handover which will support the battery power of MN with its ongoing application if the call is not regular.

Introduction Heterogeneous wireless networks include coexistence of current wireless technologies such as 2G/3G cellular, satellite, Bluetooth, LTE, 802.11, 802.16, and 802.20. This environment raises a new challenge for the study of radio resource management. Early mobile phones were limited to voice calls and SMS and packet based applications such as email. The higher data bandwidths support many more applications including video calls, audio streaming, and video streaming. The bottleneck to take care of in the design process of mobile systems is not only the wireless data rate, but even more the energy/power limitation as the customers ask for new energy-hungry services, e.g., requiring faster connections or even multiple air interfaces, and longer standby or operational times. Excessive energy consumption is limiting the evolution of smart phones as the improvement of battery capacity is quite moderate compared to the increase of the complexity due to new hardware and services. Problem Formulation Problem Definition Our project deals with reduction of power consumption during handover, Also it tries to select an appropriate target network for handover which will support the battery power of mobile node with its ongoing application. Motivation for Work Since heterogeneous network is integration of various networks Vertical handover to a high power consuming network is not desirable if the mobile terminals battery is nearly exhausted or the batteries life time is relatively short. Excessive energy/power consumption is limiting the evolution of smart phones as the improvement of battery capacity is quite moderate compared to the increase of the complexity due to new hardware and services. Network Scenario Network Scenario In generated network scenario VHO is needed for the ongoing of mobile communication when mobile node (MN) moves from one network to another network. Project Diagram The MN is assumed to be in home network i.e., GSM network and on a voice call also the user is moving in the direction as shown in the Fig 1.
