Search for Exotic Physics with the CMS detector at LHC

In this paper we present strategies and results of eight searches for exotic physics performed by the CMS experiment with 2011 and 2012 pp collision data taken at LHC energy $\sqrt{s}$ respectively 7 TeV and 8 TeV. Among them are searches for heavy gauge bosons $W$ and $Z$, heavy neutrinos, heavy quarks, Kaluza-Klein gravitons, long-lived particles, quark and lepton compositness, microscopic black holes and a number of exotic dijet resonances such as excited quarks.
