Dynamical Construction of a Core-Based Group-Shared Multicast Tree in Mobile Ad Hoc Networks
A core-based group-shared multicast tree is a shortest path tree rooted at core node that distributes packets to and from all group members. Traditionally, the bandwidth cost cons...

Primal-dual meets local search: approximating MST's with nonuniform degree bounds
We present a new bicriteria approximation algorithm for the degree-bounded minimum-cost spanning tree problem: Given an undirected graph with nonnegative edge weights and degree b...

An Optimal Broadcasting Algorithm for de Bruijn Network dBG(d, k)
Recent works have classified de Bruijn graph (dBG) based broadcasting algorithms into local broadcasting and arc-disjoint spanning trees based broadcasting. However, those algorit...

A Distributed Wakening Based Target Tracking Protocol for Wireless Sensor Networks
We propose a two layer protocol for tracking fast targets in sensor networks. At the lower layer, the Distributed Spanning Tree Algorithm (DSTA) [12] partitions the network into c...
