Wireless Sensor Networks are sets of thousands or more of sensor nodes with very small size and limited energy, scattered over particular area to sense a certain physical phenomenon. Energy constraints are the most important challenge for these networks to work efficiently for long time. Most existing clustering algorithms are applied without considering the density of region. In this paper, density-aware...
There are some classical routing protocols for WSNs (Wireless Sensor Networks) such as LEACH [3] and PEGASIS [5]. However, these protocols may have some problems in delay or energy consumption. In this paper, a novel routing protocol called DCEE (Delay-Constrained and Energy-Efficient) multi-hop routing protocol is proposed, which has high performance in delay and energy cost. In DCEE, through the...
LEACH (low-energy adaptive clustering hierarchy) is a well-known self-organizing, adaptive clustering protocol of wireless sensor networks. However it has some shortcomings when it faces such problems as the cluster construction and energy management. In this paper, LEICP (low energy intelligent clustering protocol), an improvement of the LEACH protocol is proposed to overcome the shortcomings of...
This paper considers minimum-energy routing problem in Poisson random ad-hoc networks with Nakagami-m fading channels. We first formulate an analytical model for the transmission power, subject to a certain packet reception probability, under the assumption that the users employ proper power control and slotted ALOHA protocol. Based on this, we consider five routing strategies and compare their energy...
