标题： Data Dissemination And Collection Algorithms For Collaborative Sensor Networks Using Dynamic Cluster Heads

摘要： 我们为无线传感器网络（WSNs）开发了新的数据分发和收集算法，在这些算法中，我们考虑在某一区域内随机分布的$n$个传感器节点来测量一个物理现象。 这些传感器具有有限的能量、覆盖范围不足、带宽和内存限制。 我们希望在整个网络中分发节点的数据，使得基站能够通过查询少量节点来收集感知的数据。 我们提出了两种数据分发和收集算法（DCA's）来解决这个问题。 数据分发是通过动态选择一些节点来实现的。 在时间片$t$后，所选节点将被更改，并可能在周期$T$后重复。 显示英文摘要

摘要： We develop novel data dissemination and collection algorithms for Wireless Sensor Networks (WSNs) in which we consider $n$ sensor nodes distributed randomly in a certain field to measure a physical phenomena. Such sensors have limited energy, shortage coverage range, bandwidth and memory constraints. We desire to disseminate nodes' data throughout the network such that a base station will be able to collect the sensed data by querying a small number of nodes. We propose two data dissemination and collection algorithms (DCA's) to solve this problem. Data dissemination is achieved through dynamical selection of some nodes. The selected nodes will be changed after a time slot $t$ and may be repeated after a period $T$.
