two routing protocols


Furthermore,it emulates the two routing protocols before and after improving on the simulation platform NS2,and the experiment has testified validity and feasibility of the trustful routing algorithm.The main innovation points of the thesis are as discount wedding dresses follows. 1) Study the typical secure routing protocols in WSN.The thesis analyses the trusting conditions and working principles and experiment results of various of security mechanisms,points out the feasibilities and defects of every kind of security tactics to pave the way for the research of secure custom made prom dresses trustful routing protocols.2) Study the attack types in WSN.The thesis studies the attack principles, attack characteristics and attack results of various of attack types,target-oriented analyzes which attack types appear in which routing protocols,and has a definite object in view when improving routing algorithms.3) Study the subjective logic model.The thesis innovatively applies the subjective logic model to rationally,effectively,quantitatively sell discount wedding dresses appraise the trust degree of blog new shirts 2010 sensor nodes,and reflects the different roles of various trustful nodes in the network transmission according to the different calculation regulations and evaluation rules.The thesis combines the custom made prom dresses subjective logic model and Directed Diffusion routing algorithm,establishes a network blog wedding dresses 2010 model,revises the routing form item,improves the routing algorithm,proposes the Trustful Directed Diffusion routing algorithm based on Subjective Logic,and provides several revelatory ideas for studying the secure trustful routing algorithms.
