When the use of wireless sensors network is becoming increasingly wider and deeper, its problems are also beginning to highlight. Due to the limit of wireless sensors' energy supply and the unstable channel, ensuring the reliability and speed of the transmission has become the research hot spot. With multipath or retransmission transmission mechanism, the redundancy of data transmission can be ensured...
Selective Forwarding (SF) attacks impact the data transmission integrity by not forwarding a subset of received packets from time to time. The ‘selective’ characteristic makes SF attacks hard to be distinguished from the normal packet drops or poor receptions in a volatile wireless environment. To understand this stealthy attack, an analytical model is developed to estimate the wellness of a node's...
In wireless sensor networks, multipath routing is used to alleviate reliability degradation due to multihop transmissions over error-prone wireless channels. However, multipath routing is not energy-efficient, as it requires all the nodes in the network to always be awake. To prolong the network lifetime while maintaining a certain reliability performance, we propose Sleeping Multipath Routing, which...
The unmanned nature of wireless sensor networks make them very vulnerable to the malicious attacks. Therefore, how to complete secure data collection under different conditions is the crucial issue to wireless sensor networks. There have been a few on-going research efforts about multipath routing for secure data collection. In this paper, we make full use of the broadcast message when wireless sensor...
