Emerging smartphone-based applications are generating more and more traffic load on smartphones, which makes effective reduction of energy consumption and also monetary cost for data transmissions critical. In this paper, we study how to maximally use free Wi-Fi (when available) for data transmissions, in order to improve the energy use efficiency and also reduce monetary cost of smartphones. Our...
In this paper, we propose an energy-efficient on-demand multicast routing protocol (EMP) for wireless ad hoc and sensor networks. The design objective is to prolong the network lifetime of such networks. For this purpose, EMP introduces the strategy of energy critical avoidance in the process of on-demand construction of multicast routing trees. That is, those energy-critical nodes in the network...
The connection interface of the traditional wireless sensor network device is so single that the communication ability is limited. Further more, it needs to keep the network work stability while transmitting a large number of data. In order to solve these problems, this paper designs a new universal platform and makes optimization on it. It provides some rich interface features to expand the wireless...
