Heterogeneous networks with different wireless technologies increase the availability of Internet services (i.e., cloud services). However, latest mobile phones with at least two interfaces only access these services either via WiFi or UMTS/HSPA. From user's view, an optimal use of heterogeneous networks with today's mobile phones includes seamless data transmission using Vertical HandOff (VHO) solutions. Caused by high technical and economic costs there exist no usable solutions for readily seamless data transfers. To benefit earlier from seamless service provisioning, the authors present a feasible Client baSed Handoff Management solUtion for Mobile Phones (CSH-MU) with embedded Vertical Handoff Decision Algorithm (VHDA) that considers mobile device's power consumption for WiFi and UMTS communication.
