Energy consumption of nodes is reduced by transmitting the initial code of the node, and transmitting linear independent packets received merely. After gathering node coding, ACK return along the best path to reduce the network delay. Simulation results show that delay of data transmission is reduced greatly by introducing random linear network coding for sensor network, and the improved coded mode balances the network load.10aNodes Collaboration10aRandom Linear Network Coding10aWireless sensor network1 aXiao-Xing, L.V.1 aBai-Hai, Z.  uhttp://www.scopus.com/inward/record.url?eid=2-s2.0-84892145435&partnerID=40&md5=2d72868947bda082492e18284f12ea5b01852nas a2200205   4500008004100000245007900041210006900120260000900189300001200198490000700210520118900217653001101406653002001417653001501437653002401452653001301476653002801489100001201517856011701529       2012                        eng d00aSERCID: A secure mechanism for data collection in wireless sensor networks0 aSERCID A secure mechanism for data collection in wireless sensor  c2012  a79 - 850 v103 aThe unattended nature of wireless sensor networks makes them very vulnerable to malicious attacks. An adversary can physically compromise a subset of sensor nodes in a wireless sensor network to eavesdrop information. Due to some intrinsic features of wireless sensor network, it is difficult to perform efficient intrusion detection against malicious nodes in such a resource-restricted environment. In this paper, we propose a novel secure mechanism, SERCID for wireless sensor networks. The mechanism consists of a key-based secure routing algorithm and a counter-based intrusion detection algorithm. The approach is able to protect the data collection in a wireless sensor network even if there are malicious nodes in the network. The major contribution of our work is that we present an original approach to defend wireless sensor networks against both tampering and packet-dropping attacks, for the first time. We provide a relatively simple but reliable approach to support secure data collection in wireless sensor networks. Compared with existing research efforts, the proposed approach is easy to be implemented and performed in resourceconstrained wireless sensor networks.10aAttack10aData collection10aEncryption10aIntrusion detection10aSecurity10aWireless sensor network1 aMao, Y.  uhttp://www.scopus.com/inward/record.url?eid=2-s2.0-84866465185&partnerID=40&md5=ba314ed11d14004232b2fddcd4fa4ee8
