Further ore, in this dyna ic environ ent, differ2 ent nodes offering different services ay enter and leave thenetwork at any ti e. Efficient and ti ely service discovery beco es a new task of obile Ad hoc network. Discovery of services is a crucial featurefor the usability of obile Ad hoc networks. In this paper, wesurvey the researches ofrecent years on service discovery, classify theexisting service discovery protocols of obile Ad hoc networks. Moreover, wesu arize and co parethese protocols. Based on thea2 nalysis, further research issues that still need investigation are listed.
