A new SLP based power efficient algorithm for the Wireless Sensor Network (wsn)

In this paper, we show the enhanced version of SLPv2 (Service Location Protocol version 2). It is one of the service discovery protocols in wired network, and we propose the wireless network based SLP for WSN (wireless sensor network). If a wired protocol is transferred to the wireless domain, then we have to consider some critical problems, like resource and power wall, etc. So SLP for the WSN must meet the low power consumption, low rate, and meet the endurable reliability. Thus, we suggest the ldquodynamic scope methodrdquo, and the ldquoT_ID check algorithmrdquo for the WSN based SLP. In this paper, we bound the distance by the hop count. It not only can reduce the packet exchange dramatically but also can be useful to the WSN in many different ways. The first is the low energy consumption, and second, it can reduce the bottleneck due to the Tree structure of WSN environment. Due to the reduction of bottleneck, it results in the low packet loss, and has a good throughput due to the low probability of packet collision.
