Efficient Power Saving during Handovers in Heterogeneous Network Scenario

The Next Generation of wireless networks will provide ubiquitous computing by the seamless operation of heterogeneous wireless networks. 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.
