Energy efficient multicast problem is one of important issues in ad hoc networks. In this paper, we address the energy efficient multicast problem for discrete power levels in ad hoc wireless networks. The problem of our concern is: given n nodes deployed over 2-D plane and each node v has l(v) transmission power levels and a multicast request (s,D) (clearly, when D is V∖{s}, the multicast request...
Broadcasting/Multicasting problems have been well studied in wireless ad hoc networks. However, only a few approaches take into account the low interference and energy efficiency as the optimization objective simultaneously. In this paper, we study the interference and power constrained broadcast/multicast and the delay-bounded interference and power constrained broadcast/multicast routing problems...
Flooding is one of the most fundamental operations in wireless ad hoc networks. In this paper, we study the sufficient and necessary condition of efficient flooding schemes based on only one-hop out-neighbors' information in heterogeneous ad hoc networks. We further propose an efficient flooding algorithm using one-hop out-neighbors' information that achieves the local optimality: (1) the number of...
In this paper, we discuss the energy efficient multicast problem for discrete power levels in ad hoc sensor wireless networks. The problem of our concern is: given n nodes and each node v has l(v) transmission power levels and a multicast request (s, D), how to find a multicast tree rooted at s and spanning all destinations in D such that the total energy cost of the multicast tree is minimized. This...
