Abstract — It is generally accepted that energy consump-tion is a significant design constraint for mobile handheld sys-tems, therefore motivations for methods optimizing the en-ergy consumption making better use of the restricted battery resources are evident. A novel concept of distributed task computing is previously proposed (D2VS), where the over-all idea of selective distribution of tasks among terminals is made. In this paper the optimal number of terminals for co-operative task computing in a wireless network will be inves-tigated. The paper presents an energy model for the proposed scheme. Energy consumption of the terminals with respect to their workload and the overhead of distributing tasks among terminals are taken into account. The paper shows, that the number of cooperating terminals is in general limited to a few, though alternating with respect to the various system parame-ters.
