摘要：Multi ple-path s ource rou ting protocols allow a data sou rce n ode to di stribu te the total traffic amon g available paths. In this paper, we con sider the probl em of jammin g-aware sou rce routin g in which the source node performs traffi c allocation based on empirical jammin g statistics at individual network nodes. We formulate this traffic allocation as a loss y ne twork flow optimization problem using portfolio sel ection the ory from financial stati stics. We show th at in mul tisou rce n etworks, this centralized opti mization proble m can be solved us ing a dis tribu ted algorithm based on decompositi on in network utility maximization (NUM). We demonstrate the ne twork's ability to e stimate the impact of jamming and in corporate the se estimates in to the traffic allocation proble m. Fi nally, we simu late the achievable throughput us ing ou r pro pose d traffic allocation meth od i n several scenarios
